-% and in the form of plain \TeX{}, \LaTeX{}, and \Hologo{ConTeXt} macro
-% packages that enable the direct inclusion of markdown documents inside \TeX{}
-% documents.
-%
-% Architecturally, the package consists of the \pkg{Lunamark} v0.5.0 Lua module
-% by John MacFarlane, which was slimmed down and rewritten for the needs of the
-% package. On top of \pkg{Lunamark} sits code for the plain \TeX{}, \LaTeX{},
-% and \Hologo{ConTeXt} formats by Vít Novotný.

+
+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
+% in~Brno~[@novotny15] is gratefully acknowledged.
+%
+% 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 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.

+### 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
