+<h1 id="introduction"><span class="header-section-number">1</span> Introduction</h1>
+<p>The <a href="https://ctan.org/pkg/markdown" title="CTAN: Package markdown">Markdown package</a> converts <a href="https://daringfireball.net/projects/markdown/basics/" title="Daring Fireball: Markdown Basics">markdown</a> markup to TeX commands. The functionality is provided both as a Lua module, and as plain TeX, LaTeX, and ConTeXt macro packages that can be used to directly typeset TeX documents containing markdown markup. Unlike other convertors, the Markdown package makes it easy to redefine how each and every markdown element is rendered. Creative abuse of the markdown syntax is encouraged. <i class="em em-wink"></i></p>
+<p>This document is a user manual for the <a href="https://ctan.org/pkg/markdown" title="CTAN: Package markdown">Markdown package</a>. It provides beginner tutorials and code examples. For an in-depth description of the package requirements, interfaces, and implementation, please refer to the <a href="http://mirrors.ctan.org/macros/generic/markdown/markdown.pdf" title="A Markdown Interpreter for TeX">technical documentation</a>.</p>
+<h2 id="requirements"><span class="header-section-number">1.1</span> Requirements</h2>
+<p>The package requires a working TeX distribution. <a href="https://www.tug.org/texlive/" title="TeX Live - TeX Users Group">TeX Live</a> ≥ 2013 is known to work and so are recent installation of <a href="https://miktex.org/" title="Home - MiKTeXorg">MikTeX</a>. If you are using a minimal installation of a TeX distribution, please consult the <a href="http://mirrors.ctan.org/macros/generic/markdown/markdown.pdf" title="A Markdown Interpreter for TeX">technical documentation</a> for a detailed list of required packages.</p>
+<h2 id="installation"><span class="header-section-number">1.2</span> Installation</h2>
+<p>The package comes pre-installed with <a href="https://www.tug.org/texlive/" title="TeX Live - TeX Users Group">TeX Live</a> ≥ 2016 and with recent installations of <a href="https://miktex.org/" title="Home - MiKTeXorg">MikTeX</a>. Unless you explicitly wish to use the latest version of the package, you are encouraged to skip this step.</p>
+<p>To install the package, first download the package from the repository using Git:</p>
+<div class="sourceCode"><pre class="sourceCode sh"><code class="sourceCode bash"><span class="fu">git</span> clone https://github.com/witiko/markdown</code></pre></div>
+<p>Next, enter the directory named <code>markdown</code> and interpret the file named <code>markdown.ins</code> file using a Unicode-aware TeX engine, such as XeTeX or LuaTeX:</p>
+<div class="sourceCode"><pre class="sourceCode sh"><code class="sourceCode bash"><span class="bu">cd</span> markdown
+<span class="ex">luatex</span> markdown.ins</code></pre></div>
+<p>This should produce the following files:</p>
+<ul>
+<li><code>markdown.lua</code> – the Lua module,</li>
+<li><code>markdown-cli.lua</code> – the Lua command-line interface,</li>
+<li><code>markdown.tex</code> – the plain TeX macro package,</li>
+<li><code>markdown.sty</code> – the LaTeX package, and</li>
+<li><code>t-markdown.tex</code> – the ConTeXt module.</li>
+</ul>
+<h3 id="local-installation"><span class="header-section-number">1.2.1</span> Local installation</h3>
+<p>To perform a local installation, place the above files into your TeX directory structure. This is generally where the individual files should be placed:</p>
+<ul>
+<li><code>&lt;TEXMF&gt;/tex/luatex/markdown/markdown.lua</code></li>
+<li><code>&lt;TEXMF&gt;/scripts/markdown/markdown-cli.lua</code></li>
+<li><code>&lt;TEXMF&gt;/tex/generic/markdown/markdown.tex</code></li>
+<li><code>&lt;TEXMF&gt;/tex/latex/markdown/markdown.sty</code></li>
+<li><code>&lt;TEXMF&gt;/tex/context/third/markdown/t-markdown.tex</code></li>
+</ul>
+<p>where <code>&lt;TEXMF&gt;</code> corresponds to a root of your TeX distribution, such as <code>/usr/share/texmf</code> and <code>~/texmf</code> on UN*X systems or <code>C:\Users\&lt;YOUR␣USERNAME&gt;\texmf</code> on Windows systems.

+<h1 id="examples"><span class="header-section-number">2</span> Examples</h1>
+<p>This section will show how to use the package by example.</p>
+<h2 id="lua"><span class="header-section-number">2.1</span> Lua</h2>
+<p>The Lua part of the package makes it possible to convert a markdown document into TeX commands and typeset it later when convenient. Although the typical user will not find this terribly useful and will instead use the plain TeX, LaTeX, and ConTeXt macro packages to convert and typeset the markdown documents in a single step, they will still benefit from learning the options that control the behavior of the Lua parser.</p>
+<h3 id="interfaces"><span class="header-section-number">2.1.1</span> Interfaces</h3>
+<p>The Lua part of the package exposes two interfaces – the <code>markdown</code> Lua module, and the Lua command-line interface (CLI).</p>
+<h4 id="the-lua-module"><span class="header-section-number">2.1.1.1</span> The Lua module</h4>
+<p>The <code>markdown</code> Lua module exposes the <code>new(options)</code> method, which creates a converter function from markdown to TeX. The properties of the converter function are specified by the Lua table <code>options</code>. The parameter is optional; when unspecified, the behaviour will be the same as if <code>options</code> were an empty table.</p>
+<p>Using a text editor, create a text document named <code>document.tex</code> with the following content:</p>
+<div class="sourceCode"><pre class="sourceCode tex"><code class="sourceCode latex"><span class="fu">\input</span> markdown
+<span class="fu">\input</span> lmfonts
+<span class="fu">\input</span> example
+<span class="fu">\bye</span></code></pre></div>
+<p>Using a text editor, create a text document named <code>example.lua</code> with the following content:</p>
+<div class="sourceCode"><pre class="sourceCode lua"><code class="sourceCode lua"><span class="ot">#</span>!<span class="ot">/</span>usr<span class="ot">/</span>bin<span class="ot">/</span>env texlua

+<p>Next, invoke LuaTeX from the terminal:</p>
+<div class="sourceCode"><pre class="sourceCode sh"><code class="sourceCode bash"><span class="ex">texlua</span> example.lua <span class="op">&gt;</span> example.tex
+<span class="ex">luatex</span> document.tex</code></pre></div>
+<p>A PDF document named <code>document.pdf</code> should be produced and contain the text “$\sqrt{-1}$ <em>equals</em> $i$. √-̅1̅ <em>equals</em> <span class="math inline"><em>i</em></span>.” Invoking pdfTeX should have the same effect:</p>
+<div class="sourceCode"><pre class="sourceCode sh"><code class="sourceCode bash"><span class="ex">texlua</span> example.lua <span class="op">&gt;</span> example.tex
+<span class="ex">pdftex</span> document.tex</code></pre></div>
+<hr />
+<p>Rather than use the <code>texlua</code> interpreter, we can also access the <code>markdown</code> Lua module directly from our document. Using a text editor, create a text document named <code>document.tex</code> with the following content:</p>
+<div class="sourceCode"><pre class="sourceCode tex"><code class="sourceCode latex"><span class="fu">\input</span> markdown
+<span class="fu">\input</span> lmfonts

+  local input = [[<span class="ss">$</span><span class="sc">\noexpand\sqrt</span><span class="ss">{-1}$</span> *equals* <span class="ss">$i$</span>.]]
+  tex.sprint(convert_safe(input) .. &quot; &quot; .. convert_unsafe(input)) }
+<span class="fu">\bye</span></code></pre></div>
+<p>Next, invoke LuaTeX from the terminal:</p>
+<div class="sourceCode"><pre class="sourceCode sh"><code class="sourceCode bash"><span class="ex">luatex</span> document.tex</code></pre></div>
+<p>A PDF document named <code>document.pdf</code> should be produced and contain the text “$\sqrt {-1}$ <em>equals</em> $i$. √-̅1̅ <em>equals</em> <span class="math inline"><em>i</em></span>.” In this case, we cannot use pdfTeX, because pdfTeX does not define the <code>\directlua</code> TeX command.</p>
+<h4 id="the-lua-cli"><span class="header-section-number">2.1.1.2</span> The Lua CLI</h4>
+<p>The Lua command-line interface (CLI) accepts the same options as the <code>markdown</code> Lua module, but now the options are specified as command-line parameters.</p>
+<p>Using a text editor, create a text document named <code>document.tex</code> with the following content:</p>
+<div class="sourceCode"><pre class="sourceCode tex"><code class="sourceCode latex"><span class="fu">\input</span> markdown

+
+Introduction
+============
+The [Markdown package][pkg] converts [markdown][] markup to TeX commands. The
+functionality is provided both as a Lua module, and as plain TeX, LaTeX, and
+ConTeXt macro packages that can be used to directly typeset TeX documents
+containing markdown markup. Unlike other convertors, the Markdown package
+makes it easy to redefine how each and every markdown element is rendered.
+Creative abuse of the markdown syntax is encouraged. <i class="em em-wink"></i>

+            (A Markdown Interpreter for TeX)
+
+
+Requirements
+------------
+
+The package requires a working TeX distribution. [TeX Live][] ≥ 2013 is known to
+work and so are recent installation of [MikTeX][]. If you are using a minimal
+installation of a TeX distribution, please consult the
+[technical documentation][techdoc] for a detailed list of required packages.
+
+ [TeX Live]: https://www.tug.org/texlive/ (TeX Live - TeX Users Group)
+ [MikTeX]: https://miktex.org/ (Home - MiKTeXorg)
+
+Installation
+------------
+
+The package comes pre-installed with [TeX Live][] ≥ 2016 and with recent
+installations of [MikTeX][]. Unless you explicitly wish to use the latest
+version of the package, you are encouraged to skip this step.
+
+To install the package, first download the package from the repository
+using Git:
+``` sh
+git clone https://github.com/witiko/markdown
+``````
+Next, enter the directory named `markdown` and interpret the file named
+`markdown.ins` file using a Unicode-aware TeX engine, such as XeTeX or
+LuaTeX:
+``` sh
+cd markdown
+luatex markdown.ins
+``````
+This should produce the following files:
+
+ * `markdown.lua` – the Lua module,
+ * `markdown-cli.lua` – the Lua command-line interface,
+ * `markdown.tex` – the plain TeX macro package,
+ * `markdown.sty` – the LaTeX package, and
+ * `t-markdown.tex` – the ConTeXt module.
+
+### Local installation
+
+To perform a local installation, place the above files into your TeX directory
+structure. This is generally where the individual files should be placed:
+
+ * `<TEXMF>/tex/luatex/markdown/markdown.lua`
+ * `<TEXMF>/scripts/markdown/markdown-cli.lua`
+ * `<TEXMF>/tex/generic/markdown/markdown.tex`
+ * `<TEXMF>/tex/latex/markdown/markdown.sty`
+ * `<TEXMF>/tex/context/third/markdown/t-markdown.tex`
+
+where `<TEXMF>` corresponds to a root of your TeX distribution, such as
+`/usr/share/texmf` and `~/texmf` on UN\*X systems or
+`C:\Users\<YOUR␣USERNAME>\texmf` on Windows systems. When in doubt,
+consult the manual of your TeX distribution.
+
+### Portable installation ###
+
+Alternatively, you can also store the above files in the same folder as your
+TeX document and distribute them together. This way your document can be
+portably typeset on legacy TeX distributions.
+
+
+First document
+--------------
+
+In this section, we will take the necessary steps to typeset our first markdown
+document in TeX. This will serve as our first hands-on experience with the
+package and also as a reassurance that the package has been correctly installed.
+
+### Using Lua
+
+Using a text editor, create a text document named `document.tex` with the
+following content:
+``` tex
+\input markdown
+\input hello
+\bye
+```````
+
+#### Using the Lua module
+
+Using a text editor, create a text document named `hello.lua` with the
+following content:
+``` lua
+#!/usr/bin/env texlua
+local kpse = require("kpse")
+kpse.set_program_name("luatex")
+local markdown = require("markdown")
+local convert = markdown.new()
+print(convert("Hello *world*!"))
+```````
+Next, invoke LuaTeX from the terminal:
+``` sh
+texlua hello.lua > hello.tex
+luatex document.tex
+``````
+A PDF document named `document.pdf` should be produced and contain the text
+“Hello *world*!” Invoking pdfTeX should have the same effect:
+``` sh
+texlua hello.lua > hello.tex
+pdftex document.tex
+``````
+
+#### Using the Lua CLI
+
+Using a text editor, create a text document named `hello.md` with the
+following content:
+``` md
+Hello *world*!
+``````
+Next, invoke LuaTeX from the terminal:
+``` sh
+texlua <CLI␣PATHNAME> -- hello.md hello.tex
+luatex document.tex
+``````
+where `<CLI␣PATHNAME>` corresponds to the location of the Lua CLI script file,
+such as `~/texmf/scripts/markdown/markdown-cli.lua` on UN\*X systems or
+`C:\Users\<YOUR␣USERNAME>\texmf\scripts\markdown\markdown-cli.lua` on Windows
+systems. Use the command `kpsewhich markdown-cli.lua` to locate the Lua CLI
+script file using [Kpathsea][].
+
+ [Kpathsea]: https://tug.org/kpathsea/ (Kpathsea - TeX Users Group)
+
+A PDF document named `document.pdf` should be produced and contain the text “Hello
+*world*!” Invoking pdfTeX should have the same effect:
+``` sh
+texlua <CLI␣PATHNAME> -- hello.md hello.tex
+pdftex document.tex
+``````
+
+### Using plain TeX
+
+Using a text editor, create a text document named `document.tex` with the
+following content:
+``` tex
+\input markdown
+\markdownBegin
+Hello *world*!
+\markdownEnd
+\bye
+```````
+Next, invoke LuaTeX from the terminal:
+``` sh
+luatex document.tex
+``````
+A PDF document named `document.pdf` should be produced and contain the text
+“Hello *world*!” Invoking pdfTeX should have the same effect:
+``` sh
+pdftex --shell-escape document.tex
+```````
+
+### Using LaTeX
+
+Using a text editor, create a text document named `document.tex` with the
+following content:
+``` tex
+\documentclass{article}
+\usepackage{markdown}
+\begin{document}
+\begin{markdown}
+Hello *world*!
+\end{markdown}
+\end{document}
+```````
+Next, invoke LuaTeX from the terminal:
+``` sh
+lualatex document.tex
+``````
+A PDF document named `document.pdf` should be produced and contain the text “Hello
+*world*!” Invoking pdfTeX should have the same effect:
+``` sh
+pdflatex --shell-escape document.tex
+``````
+
+***
+
+As the next step, try typesetting the example documents distributed along with
+the Markdown package:
+``` sh
+git clone https://github.com/witiko/markdown
+cd markdown/examples
+lualatex latex.tex
+``````
+A PDF document named `latex.pdf` should be produced. Open the text documents
+`latex.tex` and `example.md` in a text editor to see how the example documents
+are structured. Try changing the documents and typesetting them as follows:
+``` sh
+lualatex latex.tex
+``````
+to see the effect of your changes.
+
+### Using ConTeXt
+
+Using a text editor, create a text document named `document.tex` with the
+following content:
+``` tex
+\usemodule[t][markdown]
+\starttext
+\startmarkdown
+Hello *world*!
+\stopmarkdown
+\stoptext
+```````
+Next, invoke LuaTeX from the terminal:
+``` sh
+context document.tex
+``````
+A PDF document named `document.pdf` should be produced and contain the text “Hello
+*world*!” Invoking pdfTeX should have the same effect:
+``` sh
+texexec --passon=--shell-escape document.tex
+``````
+
+***
+
+As the next step, try typesetting the example documents distributed along with
+the Markdown package:
+``` sh
+git clone https://github.com/witiko/markdown
+cd markdown/examples
+context context.tex
+``````
+A PDF document named `context.pdf` should be produced. Open the text documents
+`context.tex` and `example.md` in a text editor to see how the example documents
+are structured. Try changing the documents and typesetting them as follows:
+``` sh
+context context.tex
+``````
+to see the effect of your changes.
+
+Examples
+========
+
+This section will show how to use the package by example.
+
+
+Lua
+---
+
+The Lua part of the package makes it possible to convert a markdown document
+into TeX commands and typeset it later when convenient. Although the typical
+user will not find this terribly useful and will instead use the plain TeX,
+LaTeX, and ConTeXt macro packages to convert and typeset the markdown documents
+in a single step, they will still benefit from learning the options that
+control the behavior of the Lua parser.
+
+
+### Interfaces
+
+The Lua part of the package exposes two interfaces – the `markdown` Lua module,
+and the Lua command-line interface (CLI).
+
+#### The Lua module
+
+The `markdown` Lua module exposes the `new(options)` method, which creates a
+converter function from markdown to TeX. The properties of the converter
+function are specified by the Lua table `options`. The parameter is optional;
+when unspecified, the behaviour will be the same as if `options` were an empty
+table.
+
+Using a text editor, create a text document named `document.tex` with the
+following content:
+``` tex
+\input markdown
+\input lmfonts
+\input example
+\bye
+```````
+Using a text editor, create a text document named `example.lua` with the
+following content:
+``` lua
+#!/usr/bin/env texlua
+local kpse = require("kpse")
+kpse.set_program_name("luatex")
+local markdown = require("markdown")
+local convert_safe = markdown.new()
+local convert_unsafe = markdown.new({hybrid = true})
+local input = [[$\sqrt{-1}$ *equals* $i$.]]
+print(convert_safe(input) .. " " .. convert_unsafe(input))
+```````
+Next, invoke LuaTeX from the terminal:
+``` sh
+texlua example.lua > example.tex
+luatex document.tex
+``````
+A PDF document named `document.pdf` should be produced and contain the text
+“\$\\sqrt{-1}\$ *equals* \$i\$. √-̅1̅ *equals* $i$.” Invoking pdfTeX should have
+the same effect:
+``` sh
+texlua example.lua > example.tex
+pdftex document.tex
+``````
+
+***
+
+Rather than use the `texlua` interpreter, we can also access the `markdown` Lua
+module directly from our document. Using a text editor, create a text document
+named `document.tex` with the following content:
+``` tex
+\input markdown
+\input lmfonts
+\directlua{
+  local markdown = require("markdown")
+  local convert_safe = markdown.new()
+  local convert_unsafe = markdown.new({hybrid = true})
+  local input = [[$\noexpand\sqrt{-1}$ *equals* $i$.]]
+  tex.sprint(convert_safe(input) .. " " .. convert_unsafe(input)) }
+\bye
+```````
+Next, invoke LuaTeX from the terminal:
+``` sh
+luatex document.tex
+```````
+A PDF document named `document.pdf` should be produced and contain the text
+“\$\\sqrt {-1}\$ *equals* \$i\$. √-̅1̅ *equals* $i$.” In this case, we cannot
+use pdfTeX, because pdfTeX does not define the `\directlua` TeX command.
+
+#### The Lua CLI
+
+The Lua command-line interface (CLI) accepts the same options as the `markdown`
+Lua module, but now the options are specified as command-line parameters.
+
+Using a text editor, create a text document named `document.tex` with the
+following content:
+``` tex
+\input markdown
+\input lmfonts
+\input safe\ \input unsafe
+\bye
+```````
+Using a text editor, create a text document named `example.md` with the
+following content:
+``` md
+$\sqrt{-1}$ *equals* $i$.
+``````
+Next, invoke LuaTeX from the terminal:
+``` sh
+texlua <CLI␣PATHNAME> -- example.md safe.tex
+texlua <CLI␣PATHNAME> hybrid=true -- example.md unsafe.tex
+luatex document.tex
+``````
+where `<CLI␣PATHNAME>` corresponds to the location of the Lua CLI script file,
+such as `~/texmf/scripts/markdown/markdown-cli.lua` on UN\*X systems or
+`C:\Users\<YOUR␣USERNAME>\texmf\scripts\markdown\markdown-cli.lua` on Windows
+systems. Use the command `kpsewhich markdown-cli.lua` to locate the Lua CLI
+script file using [Kpathsea][].
+
+A PDF document named `document.pdf` should be produced and contain the text
+“\$\\sqrt{-1}\$ *equals* \$i\$. √-̅1̅ *equals* $i$.” Invoking pdfTeX should have
+the same effect:
+``` sh
+texlua <CLI␣PATHNAME> -- example.md safe.tex
+texlua <CLI␣PATHNAME> hybrid=true -- example.md unsafe.tex
+pdftex document.tex
+``````
+
+
+### Options
+
+This section will cover the options recognized by the Lua interface. The
+interfaces of the plain TeX, LaTeX, and ConTeXt macro packages recognize these
+options as well, in addition to their own options.
+
+
+#### File and Directory Names
+
+
+##### Option `cacheDir`
+
+`cacheDir` (default value: `"."`)
+
+:    A path to the directory containing auxiliary cache files. If the last
+     segment of the path does not exist, it will be created by the Lua
+     command-line and plain TeX implementations. The Lua implementation expects
+     that the entire path already exists.
+
+     When iteratively writing and typesetting a markdown document, the cache
+     files are going to accumulate over time. You are advised to clean the
+     cache directory every now and then, or to set it to a temporary filesystem
+     (such as `/tmp` on UN*X systems), which gets periodically emptied.
+
+
+###### Lua module example {.unnumbered}
+
+Using a text editor, create a text document named `document.tex` with the
+following content:
+``` tex
+\input markdown
+\directlua{
+  local markdown = require("markdown")
+  local convert = markdown.new({cacheDir = "cache"})
+  local input = "Hello *world*!"
+  tex.sprint(convert(input)) }
+\bye
+```````
+Create an empty directory named `cache` next to our text document. Then, invoke
+LuaTeX from the terminal:
+``` sh
+luatex document.tex
+```````
+A PDF document named `document.pdf` should be produced and contain the text
+“Hello *world*!” Several cache files of the Markdown package will also be
+produced in the `cache` directory as we requested using the `cacheDir` option.
+
+###### Lua CLI example {.unnumbered}

+``````
+Next, invoke LuaTeX from the terminal:
+``` sh
+texlua <CLI␣PATHNAME> cacheDir=cache -- hello.md hello.tex
+luatex document.tex
+```````
+where `<CLI␣PATHNAME>` corresponds to the location of the Lua CLI script file,
+such as `~/texmf/scripts/markdown/markdown-cli.lua` on UN\*X systems or
+`C:\Users\<YOUR␣USERNAME>\texmf\scripts\markdown\markdown-cli.lua` on Windows
+systems. Use the command `kpsewhich markdown-cli.lua` to locate the Lua CLI
+script file using [Kpathsea][].
+
+A PDF document named `document.pdf` should be produced and contain the text
+“Hello *world*!” A directory named `cache` containing several cache files of
+the Markdown package will also be produced as we requested using the `cacheDir`

+Plain TeX
+---------
+
+The plain TeX macro package provides TeX commands for typesetting markdown
+documents that invoke the Lua parser in the background. Beside TeX commands
+that correspond to the Lua options, the macro package also provides commands
+corresponding to additional plain TeX-specific options, and so-called *token
+renderer* commands that define how the individual markdown elements will be
+typeset.

+-- your modified source file does not generate any modified file with
+-- the same name as a standard file.

 % \fi
-%
-% \section{Introduction}
-% This document is a reference manual for the \pkg{Markdown} package. It is
-% split into three sections. This section explains the purpose and the
-% background of the package and outlines its prerequisites. Section
-% \ref{sec:interfaces} describes the interfaces exposed by the package along
-% with usage notes and examples. It is aimed at the user of the package.
-% Section \ref{sec:implementation} describes the implementation of the package.
-% It is aimed at the developer of the package and the curious user.
-%
-% \subsection{About \pkg{Markdown}}
-% The \pkg{Markdown} package provides facilities for the conversion of markdown
-% markup to plain \TeX{}. These are provided both in the form of a Lua module
-% and in the form of plain \TeX{}, \LaTeX{}, and \Hologo{ConTeXt} macro
-% packages that enable the direct inclusion of markdown documents inside \TeX{}

+Introduction
+============
+The [Markdown package][pkg] converts [markdown][] markup to TeX commands. The
+functionality is provided both as a Lua module, and as plain TeX, LaTeX, and
+ConTeXt macro packages that can be used to directly typeset TeX documents
+containing markdown markup. Unlike other convertors, the Markdown package
+makes it easy to redefine how each and every markdown element is rendered.
+Creative abuse of the markdown syntax is encouraged. <i class="em em-wink"></i>

+% Acknowledgements
+%-----------------
+% The Lunamark Lua module provides speedy markdown parsing for the package. I
+% would like to thank John Macfarlane, the creator of Lunamark, for releasing
+% Lunamark under a permissive license.
+%
+% Funding by the the Faculty of Informatics at the Masaryk~University

+%
+% The \TeX{} implementation of the package draws inspiration from several
+% sources including the source code of \Hologo{LaTeX2e}, the \pkg{minted}
+% package by Geoffrey M. Poore -- which likewise tackles the issue of
+% interfacing with an external interpreter from \TeX{}, the \pkg{filecontents}
+% package by Scott Pakin, and others.

+
+Requirements
+------------
+
+The package requires a working TeX distribution. [TeX Live][] ≥ 2013 is known to
+work and so are recent installation of [MikTeX][]. If you are using a minimal
+installation of a TeX distribution, please consult the
+[technical documentation][techdoc] for a detailed list of required packages.
+
+ [TeX Live]: https://www.tug.org/texlive/ (TeX Live - TeX Users Group)
+ [MikTeX]: https://miktex.org/ (Home - MiKTeXorg)
+
+Installation
+------------
+
+The package comes pre-installed with [TeX Live][] ≥ 2016 and with recent
+installations of [MikTeX][]. Unless you explicitly wish to use the latest
+version of the package, you are encouraged to skip this step.
+
+To install the package, first download the package from the repository
+using Git:
+``` sh
+git clone https://github.com/witiko/markdown
+``````
+Next, enter the directory named `markdown` and interpret the file named
+`markdown.ins` file using a Unicode-aware TeX engine, such as XeTeX or
+LuaTeX:
+``` sh
+cd markdown
+luatex markdown.ins
+``````
+This should produce the following files:
+
+ * `markdown.lua` – the Lua module,
+ * `markdown-cli.lua` – the Lua command-line interface,
+ * `markdown.tex` – the plain TeX macro package,
+ * `markdown.sty` – the LaTeX package, and
+ * `t-markdown.tex` – the ConTeXt module.
+
+### Local installation
+
+To perform a local installation, place the above files into your TeX directory
+structure. This is generally where the individual files should be placed:
+
+ * `<TEXMF>/tex/luatex/markdown/markdown.lua`
+ * `<TEXMF>/scripts/markdown/markdown-cli.lua`
+ * `<TEXMF>/tex/generic/markdown/markdown.tex`
+ * `<TEXMF>/tex/latex/markdown/markdown.sty`
+ * `<TEXMF>/tex/context/third/markdown/t-markdown.tex`
+
+where `<TEXMF>` corresponds to a root of your TeX distribution, such as
+`/usr/share/texmf` and `~/texmf` on UN\*X systems or
+`C:\Users\<YOUR␣USERNAME>\texmf` on Windows systems. When in doubt,
+consult the manual of your TeX distribution.
+
+### Portable installation ###
+
+Alternatively, you can also store the above files in the same folder as your
+TeX document and distribute them together. This way your document can be
+portably typeset on legacy TeX distributions.

+
+First document
+--------------
+
+In this section, we will take the necessary steps to typeset our first markdown
+document in TeX. This will serve as our first hands-on experience with the
+package and also as a reassurance that the package has been correctly installed.
+
+### Using Lua
+
+Using a text editor, create a text document named `document.tex` with the
+following content:
+``` tex
+\input markdown
+\input hello
+\bye
+```````
+
+#### Using the Lua module
+
+Using a text editor, create a text document named `hello.lua` with the
+following content:
+``` lua
+#!/usr/bin/env texlua
+local kpse = require("kpse")
+kpse.set_program_name("luatex")
+local markdown = require("markdown")
+local convert = markdown.new()
+print(convert("Hello *world*!"))
+```````
+Next, invoke LuaTeX from the terminal:
+``` sh
+texlua hello.lua > hello.tex
+luatex document.tex
+``````
+A PDF document named `document.pdf` should be produced and contain the text
+“Hello *world*!” Invoking pdfTeX should have the same effect:
+``` sh
+texlua hello.lua > hello.tex
+pdftex document.tex
+``````
+
+#### Using the Lua CLI
+
+Using a text editor, create a text document named `hello.md` with the
+following content:
+``` md
+Hello *world*!
+``````
+Next, invoke LuaTeX from the terminal:
+``` sh
+texlua <CLI␣PATHNAME> -- hello.md hello.tex
+luatex document.tex
+``````
+where `<CLI␣PATHNAME>` corresponds to the location of the Lua CLI script file,
+such as `~/texmf/scripts/markdown/markdown-cli.lua` on UN\*X systems or
+`C:\Users\<YOUR␣USERNAME>\texmf\scripts\markdown\markdown-cli.lua` on Windows
+systems. Use the command `kpsewhich markdown-cli.lua` to locate the Lua CLI
+script file using [Kpathsea][].
+
+ [Kpathsea]: https://tug.org/kpathsea/ (Kpathsea - TeX Users Group)
+
+A PDF document named `document.pdf` should be produced and contain the text “Hello
+*world*!” Invoking pdfTeX should have the same effect:
+``` sh
+texlua <CLI␣PATHNAME> -- hello.md hello.tex
+pdftex document.tex
+``````
+
+### Using plain TeX
+
+Using a text editor, create a text document named `document.tex` with the
+following content:
+``` tex
+\input markdown
+\markdownBegin
+Hello *world*!
+\markdownEnd
+\bye
+```````
+Next, invoke LuaTeX from the terminal:
+``` sh
+luatex document.tex
+``````
+A PDF document named `document.pdf` should be produced and contain the text
+“Hello *world*!” Invoking pdfTeX should have the same effect:
+``` sh
+pdftex --shell-escape document.tex
+```````
+
+### Using LaTeX
+
+Using a text editor, create a text document named `document.tex` with the
+following content:
+``` tex
+\documentclass{article}
+\usepackage{markdown}
+\begin{document}
+\begin{markdown}
+Hello *world*!
+\end{markdown}
+\end{document}
+```````
+Next, invoke LuaTeX from the terminal:
+``` sh
+lualatex document.tex
+``````
+A PDF document named `document.pdf` should be produced and contain the text “Hello
+*world*!” Invoking pdfTeX should have the same effect:
+``` sh
+pdflatex --shell-escape document.tex
+``````
+
+***
+
+As the next step, try typesetting the example documents distributed along with
+the Markdown package:
+``` sh
+git clone https://github.com/witiko/markdown
+cd markdown/examples
+lualatex latex.tex
+``````
+A PDF document named `latex.pdf` should be produced. Open the text documents
+`latex.tex` and `example.md` in a text editor to see how the example documents
+are structured. Try changing the documents and typesetting them as follows:
+``` sh
+lualatex latex.tex
+``````
+to see the effect of your changes.
+
+### Using ConTeXt
+
+Using a text editor, create a text document named `document.tex` with the
+following content:
+``` tex
+\usemodule[t][markdown]
+\starttext
+\startmarkdown
+Hello *world*!
+\stopmarkdown
+\stoptext
+```````
+Next, invoke LuaTeX from the terminal:
+``` sh
+context document.tex
+``````
+A PDF document named `document.pdf` should be produced and contain the text “Hello
+*world*!” Invoking pdfTeX should have the same effect:
+``` sh
+texexec --passon=--shell-escape document.tex
+``````
+
+***
+
+As the next step, try typesetting the example documents distributed along with

+---
+
+The Lua part of the package makes it possible to convert a markdown document
+into TeX commands and typeset it later when convenient. Although the typical
+user will not find this terribly useful and will instead use the plain TeX,
+LaTeX, and ConTeXt macro packages to convert and typeset the markdown documents
+in a single step, they will still benefit from learning the options that
+control the behavior of the Lua parser.

+
+### Interfaces
+
+The Lua part of the package exposes two interfaces – the `markdown` Lua module,
+and the Lua command-line interface (CLI).
+
+#### The Lua module
+
+The `markdown` Lua module exposes the `new(options)` method, which creates a
+converter function from markdown to TeX. The properties of the converter
+function are specified by the Lua table `options`. The parameter is optional;
+when unspecified, the behaviour will be the same as if `options` were an empty
+table.
+
+Using a text editor, create a text document named `document.tex` with the
+following content:
+``` tex
+\input markdown
+\input lmfonts
+\input example
+\bye
+```````
+Using a text editor, create a text document named `example.lua` with the
+following content:
+``` lua
+#!/usr/bin/env texlua
+local kpse = require("kpse")
+kpse.set_program_name("luatex")
+local markdown = require("markdown")
+local convert_safe = markdown.new()
+local convert_unsafe = markdown.new({hybrid = true})
+local input = [[$\sqrt{-1}$ *equals* $i$.]]
+print(convert_safe(input) .. " " .. convert_unsafe(input))
+```````
+Next, invoke LuaTeX from the terminal:
+``` sh
+texlua example.lua > example.tex
+luatex document.tex
+``````
+A PDF document named `document.pdf` should be produced and contain the text
+“\$\\sqrt{-1}\$ *equals* \$i\$. √-̅1̅ *equals* $i$.” Invoking pdfTeX should have
+the same effect:
+``` sh
+texlua example.lua > example.tex
+pdftex document.tex
+``````
+
+***
+
+Rather than use the `texlua` interpreter, we can also access the `markdown` Lua
+module directly from our document. Using a text editor, create a text document
+named `document.tex` with the following content:
+``` tex
+\input markdown
+\input lmfonts
+\directlua{
+  local markdown = require("markdown")
+  local convert_safe = markdown.new()
+  local convert_unsafe = markdown.new({hybrid = true})
+  local input = [[$\noexpand\sqrt{-1}$ *equals* $i$.]]
+  tex.sprint(convert_safe(input) .. " " .. convert_unsafe(input)) }
+\bye
+```````
+Next, invoke LuaTeX from the terminal:
+``` sh
+luatex document.tex
+```````
+A PDF document named `document.pdf` should be produced and contain the text
+“\$\\sqrt {-1}\$ *equals* \$i\$. √-̅1̅ *equals* $i$.” In this case, we cannot
+use pdfTeX, because pdfTeX does not define the `\directlua` TeX command.
+
+#### The Lua CLI
+
+The Lua command-line interface (CLI) accepts the same options as the `markdown`
+Lua module, but now the options are specified as command-line parameters.
+
+Using a text editor, create a text document named `document.tex` with the
+following content:
+``` tex
+\input markdown
+\input lmfonts
+\input safe\ \input unsafe
+\bye
+```````
+Using a text editor, create a text document named `example.md` with the
+following content:
+``` md
+$\sqrt{-1}$ *equals* $i$.
+``````
+Next, invoke LuaTeX from the terminal:
+``` sh
+texlua <CLI␣PATHNAME> -- example.md safe.tex
+texlua <CLI␣PATHNAME> hybrid=true -- example.md unsafe.tex
+luatex document.tex
+``````
+where `<CLI␣PATHNAME>` corresponds to the location of the Lua CLI script file,
+such as `~/texmf/scripts/markdown/markdown-cli.lua` on UN\*X systems or
+`C:\Users\<YOUR␣USERNAME>\texmf\scripts\markdown\markdown-cli.lua` on Windows
+systems. Use the command `kpsewhich markdown-cli.lua` to locate the Lua CLI
+script file using [Kpathsea][].
+
+A PDF document named `document.pdf` should be produced and contain the text
+“\$\\sqrt{-1}\$ *equals* \$i\$. √-̅1̅ *equals* $i$.” Invoking pdfTeX should have
+the same effect:
+``` sh
+texlua <CLI␣PATHNAME> -- example.md safe.tex
+texlua <CLI␣PATHNAME> hybrid=true -- example.md unsafe.tex
+pdftex document.tex
+``````
