+# MD4C Readme
+
+* Home: http://github.com/mity/md4c
+* Wiki: http://github.com/mity/md4c/wiki
+* Issue tracker: http://github.com/mity/md4c/issues
+
+MD4C stands for "Markdown for C" and that's exactly what this project is about.
+
+
+## What is Markdown
+
+In short, Markdown is the markup language this `README.md` file is written in.
+
+The following resources can explain more if you are unfamiliar with it:
+* [Wikipedia article](http://en.wikipedia.org/wiki/Markdown)
+* [CommonMark site](http://commonmark.org)
+
+
+## What is MD4C
+
+MD4C is Markdown parser implementation in C, with the following features:
+
+* **Compliance:** Generally, MD4C aims to be compliant to the latest version of
+  [CommonMark specification](http://spec.commonmark.org/). Currently, we are
+  fully compliant to CommonMark 0.31.
+
+* **Extensions:** MD4C supports some commonly requested and accepted extensions.
+  See below.
+
+* **Performance:** MD4C is [very fast](https://talk.commonmark.org/t/2520).
+
+* **Compactness:** MD4C parser is implemented in one source file and one header
+  file. There are no dependencies other than standard C library.
+
+* **Embedding:** MD4C parser is easy to reuse in other projects, its API is
+  very straightforward: There is actually just one function, `md_parse()`.
+
+* **Push model:** MD4C parses the complete document and calls few callback
+  functions provided by the application to inform it about a start/end of
+  every block, a start/end of every span, and with any textual contents.
+
+* **Portability:** MD4C builds and works on Windows and POSIX-compliant OSes.
+  (It should be simple to make it run also on most other platforms, at least as
+  long as the platform provides C standard library, including a heap memory
+  management.)
+
+* **Encoding:** MD4C by default expects UTF-8 encoding of the input document.
+  But it can be compiled to recognize ASCII-only control characters (i.e. to
+  disable all Unicode-specific code), or (on Windows) to expect UTF-16 (i.e.
+  what is on Windows commonly called just "Unicode"). See more details below.
+
+* **Permissive license:** MD4C is available under the [MIT license](LICENSE.md).
+
+
+## Using MD4C
+
+### Parsing Markdown
+
+If you need just to parse a Markdown document, you need to include `md4c.h`
+and link against MD4C library (`-lmd4c`); or alternatively add `md4c.[hc]`
+directly to your code base as the parser is only implemented in the single C
+source file.
+
+The main provided function is `md_parse()`. It takes a text in the Markdown
+syntax and a pointer to a structure which provides pointers to several callback
+functions.
+
+As `md_parse()` processes the input, it calls the callbacks (when entering or
+leaving any Markdown block or span; and when outputting any textual content of
+the document), allowing application to convert it into another format or render
+it onto the screen.
+
+
+### Converting to HTML
+
+If you need to convert Markdown to HTML, include `md4c-html.h` and link against
+MD4C-HTML library (`-lmd4c-html`); or alternatively add the sources `md4c.[hc]`,
+`md4c-html.[hc]` and `entity.[hc]` into your code base.
+
+To convert a Markdown input, call `md_html()` function. It takes the Markdown
+input and calls the provided callback function. The callback is fed with
+chunks of the HTML output. Typical callback implementation just appends the
+chunks into a buffer or writes them to a file.
+
+
+## Markdown Extensions
+
+The default behavior is to recognize only Markdown syntax defined by the
+[CommonMark specification](http://spec.commonmark.org/).
+
+However, with appropriate flags, the behavior can be tuned to enable some
+extensions:
+
+* With the flag `MD_FLAG_COLLAPSEWHITESPACE`, a non-trivial whitespace is
+  collapsed into a single space.
+
+* With the flag `MD_FLAG_TABLES`, GitHub-style tables are supported.
+
+* With the flag `MD_FLAG_TASKLISTS`, GitHub-style task lists are supported.
+
+* With the flag `MD_FLAG_STRIKETHROUGH`, strike-through spans are enabled
+  (text enclosed in tilde marks, e.g. `~foo bar~`).
+
+* With the flag `MD_FLAG_PERMISSIVEURLAUTOLINKS` permissive URL autolinks
+  (not enclosed in `<` and `>`) are supported.
+
+* With the flag `MD_FLAG_PERMISSIVEEMAILAUTOLINKS`, permissive e-mail
+  autolinks (not enclosed in `<` and `>`) are supported.
+
+* With the flag `MD_FLAG_PERMISSIVEWWWAUTOLINKS` permissive WWW autolinks
+  without any scheme specified (e.g. `www.example.com`) are supported. MD4C
+  then assumes `http:` scheme.
+
+* With the flag `MD_FLAG_LATEXMATHSPANS` LaTeX math spans (`$...$`) and
+  LaTeX display math spans (`$$...$$`) are supported. (Note though that the
+  HTML renderer outputs them verbatim in a custom tag `<x-equation>`.)
+
+* With the flag `MD_FLAG_WIKILINKS`, wiki-style links (`[[link label]]` and
+  `[[target article|link label]]`) are supported. (Note that the HTML renderer
+  outputs them in a custom tag `<x-wikilink>`.)
+
+* With the flag `MD_FLAG_UNDERLINE`, underscore (`_`) denotes an underline
+  instead of an ordinary emphasis or strong emphasis.
+
+Few features of CommonMark (those some people see as mis-features) may be
+disabled with the following flags:
+
+* With the flag `MD_FLAG_NOHTMLSPANS` or `MD_FLAG_NOHTMLBLOCKS`, raw inline
+  HTML or raw HTML blocks respectively are disabled.
+
+* With the flag `MD_FLAG_NOINDENTEDCODEBLOCKS`, indented code blocks are
+  disabled.
+
+
+## Input/Output Encoding
+
+The CommonMark specification declares that any sequence of Unicode code points
+is a valid CommonMark document.
+
+But, under a closer inspection, Unicode plays any role in few very specific
+situations when parsing Markdown documents:
+
+1. For detection of word boundaries when processing emphasis and strong
+   emphasis, some classification of Unicode characters (whether it is
+   a whitespace or a punctuation) is needed.
+
+2. For (case-insensitive) matching of a link reference label with the
+   corresponding link reference definition, Unicode case folding is used.
+
+3. For translating HTML entities (e.g. `&amp;`) and numeric character
+   references (e.g. `&#35;` or `&#xcab;`) into their Unicode equivalents.
+
+   However note MD4C leaves this translation on the renderer/application; as
+   the renderer is supposed to really know output encoding and whether it
+   really needs to perform this kind of translation. (For example, when the
+   renderer outputs HTML, it may leave the entities untranslated and defer the
+   work to a web browser.)
+
+MD4C relies on this property of the CommonMark and the implementation is, to
+a large degree, encoding-agnostic. Most of MD4C code only assumes that the
+encoding of your choice is compatible with ASCII. I.e. that the codepoints
+below 128 have the same numeric values as ASCII.
+
+Any input MD4C does not understand is simply seen as part of the document text
+and sent to the renderer's callback functions unchanged.
+
+The two situations (word boundary detection and link reference matching) where
+MD4C has to understand Unicode are handled as specified by the following
+preprocessor macros (as specified at the time MD4C is being built):
+
+* If preprocessor macro `MD4C_USE_UTF8` is defined, MD4C assumes UTF-8 for the
+  word boundary detection and for the case-insensitive matching of link labels.
+
+  When none of these macros is explicitly used, this is the default behavior.
+
+* On Windows, if preprocessor macro `MD4C_USE_UTF16` is defined, MD4C uses
+  `WCHAR` instead of `char` and assumes UTF-16 encoding in those situations.
+  (UTF-16 is what Windows developers usually call just "Unicode" and what
+  Win32API generally works with.)
+
+  Note that because this macro affects also the types in `md4c.h`, you have
+  to define the macro both when building MD4C as well as when including
+  `md4c.h`.
+
+  Also note this is only supported in the parser (`md4c.[hc]`). The HTML
+  renderer does not support this and you will have to write your own custom
+  renderer to use this feature.
+
+* If preprocessor macro `MD4C_USE_ASCII` is defined, MD4C assumes nothing but
+  an ASCII input.
+
+  That effectively means that non-ASCII whitespace or punctuation characters
+  won't be recognized as such and that link reference matching will work in
+  a case-insensitive way only for ASCII letters (`[a-zA-Z]`).
+
+
+## Documentation
+
+The API of the parser is quite well documented in the comments in the `md4c.h`.
+Similarly, the markdown-to-html API is described in its header `md4c-html.h`.
+
+There is also [project wiki](http://github.com/mity/md4c/wiki) which provides
+some more comprehensive documentation. However note it is incomplete and some
+details may be somewhat outdated.
+
+
+## FAQ
+
+**Q: How does MD4C compare to other Markdown parsers?**
+
+**A:** Some other implementations combine Markdown parser and HTML generator
+into a single entangled code hidden behind an interface which just allows the
+conversion from Markdown to HTML. They are often unusable if you want to
+process the input in any other way.
+
+Second, most parsers (if not all of them; at least within the scope of C/C++
+language) are full DOM-like parsers: They construct abstract syntax tree (AST)
+representation of the whole Markdown document. That takes time and it leads to
+bigger memory footprint.
+
+Building AST is completely fine as long as you need it. If you don't, there is
+a very high chance that using MD4C will be substantially faster and less hungry
+in terms of memory consumption.
+
+Last but not least, some Markdown parsers are implemented in a naive way. When
+fed with a [smartly crafted input pattern](test/pathological_tests.py), they
+may exhibit quadratic (or even worse) parsing times. What MD4C can still parse
+in a fraction of second may turn into long minutes or possibly hours with them.
+Hence, when such a naive parser is used to process an input from an untrusted
+source, the possibility of denial-of-service attacks becomes a real danger.
+
+A lot of our effort went into providing linear parsing times no matter what
+kind of crazy input MD4C parser is fed with. (If you encounter an input pattern
+which leads to a sub-linear parsing times, please do not hesitate and report it
+as a bug.)
+
+**Q: Does MD4C perform any input validation?**
+
+**A:** No. And we are proud of it. :-)
+
+CommonMark specification states that any sequence of Unicode characters is
+a valid Markdown document. (In practice, this more or less always means UTF-8
+encoding.)
+
+In other words, according to the specification, it does not matter whether some
+Markdown syntax construction is in some way broken or not. If it's broken, it
+won't be recognized and the parser should see it just as a verbatim text.
+
+MD4C takes this a step further: It sees any sequence of bytes as a valid input,
+following completely the GIGO philosophy (garbage in, garbage out). I.e. any
+ill-formed UTF-8 byte sequence will propagate to the respective callback as
+a part of the text.
+
+If you need to validate that the input is, say, a well-formed UTF-8 document,
+you have to do it on your own. The easiest way how to do this is to simply
+validate the whole document before passing it to the MD4C parser.
