+# Introduction
+
+`TeX4ebook` is bundle of lua scripts and `LaTeX` packages for conversion of
+LaTeX files to ebook formats, for example `epub`, `mobi` and `epub3`. `tex4ht`
+is used as conversion engine. 
+
+Note that while `mobi` is supported by Amazon Kindle, most widespread ebook 
+reader, it doesn't support `mathml` and this means that math must re represented
+as images. The same is true for `epub`. This is not a good thing, especially 
+for inline math, as you may experience wrong baselines. If your ebook contains
+math, the only correct solution is to produce `epub3`, as it supports `mathml`.
+The issue with `epub3` is, that majority of `e-ink` ebook readers doesn't 
+support this format, reader applications exists mainly for Android and Apple 
+devices. For books which contains mainly prose, all formats should be suitable,
+but `epub3` supports most features from web standards, such as `CSS`. 
+
+As with `tex4ht`, the emphasis is on conversion of document's logical structure
+and metadata, basic visual appearance is preserved as well, but you should use
+custom configurations if you want to make the document more visually appealing.
+You can include custom `CSS` or fonts in configuration files.
+
+## License
+
+Permission is granted to copy, distribute and/or modify this software
+under the terms of the LaTeX Project Public License, version 1.3.
+
+
+# Usage
+
+
+Run on the command line:
+
+    tex4ebook [options] filename
+
+You don't have to modify your source files unless you want to use commands
+defined by `tex4ebook` in the document, or when your document uses some
+unsupported package like `fontspec` (see details bellow how to solve this
+issue).
+
+If you want to use `tex4ebook` commands, add this line to your document
+preamble:
+
+    \usepackage{tex4ebook}
+
+but it is optional. You shouldn't need to modify your \TeX\ files
+
+## Available commands
+
+- `\coverimage{coverimage.name}` - include cover image to the document. 
+
+# Command line options
+
+-c,--config 
+
+:    specify custom config file for `tex4ht`
+
+   **example config file**: File `sample.cfg`
+  
+  
+      \Preamble{xhtml}
+      \CutAt{section}
+      \begin{document}
+      \EndPreamble
+  
+  run 
+  
+      tex4ebook -c sample filename.tex
+  
+  This config file will create `xhtml` file for every section. Note that this
+  behaviour is default.
+
+-e,--build-file (default nil)  
+
+:    Specify [make4ht build file](https://github.com/michal-h21/make4ht#build-file).
+     Defaulf build file filename is `filename.mk4`, use this option when it has
+     different filename.
+  
+-f,--format (default epub) 
+
+:    Output format. epub, epub3 and mobi are supported.
+
+-l,--lua
+
+:    Runs htlualatex instead of htlatex.
+
+-m,--mode (default default)
+
+:    This set `mode` variable, accessible in the build file. Default supported
+     values are `default` and `draft`. In `draft` mode, document is compiled
+     only once, instead of three times.
+
+-r,--resolution 
+
+:    Resolution of generated images, for example math. It should meet resolution
+     of target devices, which is usually about 167 ppi.
+
+-s,--shell-escape
+
+:     Enable shell escape in htlatex run. This may be needed if you run external
+      commands from your source files.
+
+t,--tidy
+
+:     Run tidy on output html files.
+
+
+# Configuration
+
+`tex4ebook` uses [tex4ht](http://www.tug.org/tex4ht/) for conversion from LaTeX
+to html. `tex4ht` is highly configurable using config files. Basic config file
+structure is
+
+    \Preamble{xhtml, comma separated list of options}
+    ...
+    \begin{document}
+    ...
+    \EndPreamble
+
+Basic info about command configurations can be found in a work-in-progres 
+[tex4ht tutorial](https://github.com/michal-h21/helpers4ht/wiki/tex4ht-tutorial)
+, [tex4ht documentation](http://www.tug.org/applications/tex4ht/mn11.html), 
+and in series of blogposts on CV Radhakrishnan's blog:
+[Configure part 1](http://www.cvr.cc/?p=323), 
+[Configure part 2](http://www.cvr.cc/?p=362), 
+[Low level commands](http://www.cvr.cc/?p=482). 
+Available options for `\Preamble` command are listed in the article 
+[TeX4ht: options](http://www.cvr.cc/?p=504).
+
+Great source of tips for `tex4ht` configuring is [tex4ht tag on TeX.sx](http://tex.stackexchange.com/questions/tagged/tex4ht), there is also a [tag for tex4ebook](http://tex.stackexchange.com/questions/tagged/tex4ebook).
+
+Examples of interesting questions are 
+[including images and fonts in ebooks](including images and fonts in ebooks) 
+or [setting image size in em units instead of pt](http://tex.stackexchange.com/a/195718/2891).
+
+## Provided configurations
+
+`tex4ebook` provides some configurations for your usage:
+
+    \Configure{UniqueIdentifier}{identifier}
+
+
+Every epub file should have unique identifier, like ISBN, DOI, URI etc. 
+Default identifier is URI, with value `http://example.com/\jobname`.
+
+    \Configure{OpfScheme}{URI}
+
+Type of unique identifier, default type is URI. It is
+used only in epub, it is deprecated for `epub3`
+
+    \Configure{CoverImage}{before cover image}{after cover image}
+
+By default, cover image is inserted in `<div class="cover-image">` element, 
+you may use this configuration option to insert different markup, 
+or even to place the cover image to standalone page.
+
+
+    \Configure{CoverMimeType}{mime type of cover image}
+
+Default value is `image/png`, change this value if you use other image 
+type than `png`.
+
+If you don't want to include the cover image in the document, use command 
+
+    \CoverMetadata{filename}
+
+in the config file.
+
+    \Configure{OpfMetadata}{item element}
+
+Add item to `<metadata>` section in the `OPF` file.
+
+    \Configure{OpfManifest}{maifest element}
+
+Add item to `<manifest>` section in the `OPF` file.
+
+    \Configure{xmlns}{prefix}{uri}
+
+Add xml name space to `xhtml` files. Useful in `EPUB 3`
+
+
+
+## Commands available in config files
+
+`\OpfRegisterFile[filename]`
+
+:    register file in the `OPF` file. Current output file is added by default.
+
+`\OpfAddProperty{property type}`
+
+:    add `EPUB3` property for the current file. See [EPUB3 spec](http://www.idpf.org/epub/301/spec/epub-publications.html#sec-item-property-values)
+
+`\OpfGuide[filename]{title}{type}`
+
+:    Add file to the `<guide>` section in the `OPF` file. See  [Where do you start an ePUB and what is the `<guide>` section of the .OPF file?](http://epubsecrets.com/where-do-you-start-an-epub-and-what-is-the-guide-section-of-the-opf-file.php) for some details. Note that `<guide>` is deprecated in `EPUB 3`.
+
+## Build files
+
+`tex4ebook` uses [make4ht](https://github.com/michal-h21/make4ht) as a build
+system. See `make4ht` documentation for details on build files. 
+
+# Troubleshooting
+
+When compilation of the document breaks with error during `LaTeX` run, it may
+be caused by some problem in `tex4ht` configuration. Comment out line
+`\usepackage{tex4ebook}` in your source file and run command:
+
+    htlatex filename 
+
+if same error as in `tex4ebook` run arises, the problem is in some `tex4ht`
+configuration. Try to identify the source of problem and if you cannot find the
+solution, make minimal example showing the error and ask for help either on
+[tex4ht mailinglist](http://tug.org/mailman/listinfo/tex4ht) or on
+[TeX-sx](http://tex.stackexchange.com/). 
+
+## Fontspec
+
+`tex4ht` currently doesn't support `fontspec` and open type fonts. At this
+moment, workaround for this is to modify your source file and conditionaly
+include fontspec and any other conflicting packages only when document is not
+processed with `tex4ht`. 
+
+Sample:
+
+    \documentclass{article}
+    \makeatletter
+    \@ifpackageloaded{tex4ht}{%
+    % Packages for tex4ht unicode support
+    \usepackage[utf8]{inputenc}
+    \usepackage[T1]{fontenc}
+    \usepackage[english,czech]{babel}
+    }{%
+    % Packages for xelatex
+    \usepackage{fontspec}
+    \usepackage{polyglossia}
+    \setmainfont{Latin Modern Roman}
+    }
+    \makeatother
+
+Drawback is that not all characters of unicode range are supported with
+`inputenc`. For some solutions of this limitation, see a thread on [tex4ht
+mailinglist](http://tug.org/pipermail/tex4ht/2013q1/000719.html)
+
+## Validation
+
+In case of successful compilation, use command line tool `epubcheck` to check 
+whether your document doesn't contain any errors.
+
+Type 
+ 
+    epubcheck filename.epub
+
+### Common validation issues:
+
+-  WARNING: filename.epub: item (OEBPS/foo.boo) exists in the zip file, but is
+not declared in the OPF file
+
+  Delete the `filename-(epub|epub3|mobi)` folder and `filename.epub`. Then
+  run `tex4ebook` again.
+
+- WARNING(ACC-009): hsmmt10t.epub/OEBPS/hsmmt10tch17.xhtml(235,15): MathML should either have an alt text attribute or annotation-xml child element.
+
+  This is accessibility message. Unless you use some macro with annotations for
+  each math instance, you will get lot of these messages. Try to use 
+  `epubcheck -e` to print only serious errors.

+\section{Troubleshooting}\label{troubleshooting}
+
+When compilation of the document breaks with error during \texttt{LaTeX}
+run, it may be caused by some problem in \texttt{tex4ht} configuration.
+Comment out line \texttt{\textbackslash{}usepackage\{tex4ebook\}} in
+your source file and run command:
+
+\begin{verbatim}
+htlatex filename 
+\end{verbatim}
+
+if same error as in \texttt{tex4ebook} run arises, the problem is in
+some \texttt{tex4ht} configuration. Try to identify the source of
+problem and if you cannot find the solution, make minimal example
+showing the error and ask for help either on
+\href{http://tug.org/mailman/listinfo/tex4ht}{tex4ht mailinglist} or on

+\subsection{Fontspec}\label{fontspec}
+
+\texttt{tex4ht} currently doesn't support \texttt{fontspec} and open
+type fonts. At this moment, workaround for this is to modify your source
+file and conditionaly include fontspec and any other conflicting
+packages only when document is not processed with \texttt{tex4ht}.
+
+Sample:
+
+\begin{verbatim}
+\documentclass{article}
+\makeatletter
+\@ifpackageloaded{tex4ht}{%
+% Packages for tex4ht unicode support
+\usepackage[utf8]{inputenc}
+\usepackage[T1]{fontenc}
+\usepackage[english,czech]{babel}
+}{%
+% Packages for xelatex
+\usepackage{fontspec}
+\usepackage{polyglossia}
+\setmainfont{Latin Modern Roman}
+}
+\makeatother
+\end{verbatim}
+
+Drawback is that not all characters of unicode range are supported with
+\texttt{inputenc}. For some solutions of this limitation, see a thread
+on \href{http://tug.org/pipermail/tex4ht/2013q1/000719.html}{tex4ht
+mailinglist}
+
+\subsection{Validation}\label{validation}
+
+In case of successful compilation, use command line tool
+\texttt{epubcheck} to check whether your document doesn't contain any
+errors.
+
+Type
+
+\begin{verbatim}
+epubcheck filename.epub
+\end{verbatim}
+
+\subsubsection{Common validation
+issues:}\label{common-validation-issues}
+
+\begin{itemize}
+\itemsep1pt\parskip0pt\parsep0pt
+\item
+  WARNING: filename.epub: item (OEBPS/foo.boo) exists in the zip file,
+  but is not declared in the OPF file
+\end{itemize}
+
+Delete the \texttt{filename-(epub\textbar{}epub3\textbar{}mobi)} folder
+and \texttt{filename.epub}. Then run \texttt{tex4ebook} again.
+
+\begin{itemize}
+\itemsep1pt\parskip0pt\parsep0pt
+\item
+  WARNING(ACC-009): hsmmt10t.epub/OEBPS/hsmmt10tch17.xhtml(235,15):
+  MathML should either have an alt text attribute or annotation-xml
+  child element.
+\end{itemize}
+
+This is accessibility message. Unless you use some macro with
+annotations for each math instance, you will get lot of these messages.
+Try to use \texttt{epubcheck -e} to print only serious errors.
