+
+Features
+--------
+
+* **Pure Python**. Tested in Python 2.7, Python 3.5+ and PyPy.
+* **Very Fast**. It is the fastest in all **pure Python** markdown parsers.
+* **More Features**. Table, footnotes, autolink, fenced code etc.
+
+View the `benchmark results <https://github.com/lepture/mistune/issues/1>`_.
+
+Installation
+------------
+
+Installing mistune with pip::
+
+    $ pip install mistune
+
+
+Mistune can be faster, if you compile with cython::
+
+    $ pip install cython mistune
+
+
+Basic Usage
+-----------
+
+A simple API that render a markdown formatted text:
+
+.. code:: python
+
+    import mistune
+
+    mistune.markdown('I am using **mistune markdown parser**')
+    # output: <p>I am using <strong>mistune markdown parser</strong></p>
+
+If you care about performance, it is better to re-use the Markdown instance:
+
+.. code:: python
+
+    import mistune
+
+    markdown = mistune.Markdown()
+    markdown('I am using **mistune markdown parser**')
+
+Mistune has enabled all features by default. You don't have to configure
+anything. But there are options for you to change the parser behaviors.
+
+
+Options
+-------
+
+Here is a list of all options that will affect the rendering results,
+configure them with ``mistune.Renderer``:
+
+.. code:: python
+
+    renderer = mistune.Renderer(escape=True, hard_wrap=True)
+    # use this renderer instance
+    markdown = mistune.Markdown(renderer=renderer)
+    markdown(text)
+
+* **escape**: if set to *False*, all raw html tags will not be escaped.
+* **hard_wrap**: if set to *True*, it will has GFM line breaks feature.
+  All new lines will be replaced with ``<br>`` tag
+* **use_xhtml**: if set to *True*, all tags will be in xhtml, for example: ``<hr />``.
+* **parse_block_html**: parse text only in block level html.
+* **parse_inline_html**: parse text only in inline level html.
+
+When using the default renderer, you can use one of the following shortcuts::
+
+    mistune.markdown(text, escape=True, hard_wrap=True)
+
+    markdown = mistune.Markdown(escape=True, hard_wrap=True)
+    markdown(text)
+
+
+Renderer
+--------
+
+Like misaka/sundown, you can influence the rendering by custom renderers.
+All you need to do is subclassing a `Renderer` class.
+
+Here is an example of code highlighting:
+
+.. code:: python
+
+    import mistune
+    from pygments import highlight
+    from pygments.lexers import get_lexer_by_name
+    from pygments.formatters import html
+
+    class HighlightRenderer(mistune.Renderer):
+        def block_code(self, code, lang):
+            if not lang:
+                return '\n<pre><code>%s</code></pre>\n' % \
+                    mistune.escape(code)
+            lexer = get_lexer_by_name(lang, stripall=True)
+            formatter = html.HtmlFormatter()
+            return highlight(code, lexer, formatter)
+
+    renderer = HighlightRenderer()
+    markdown = mistune.Markdown(renderer=renderer)
+    print(markdown('```python\nassert 1 == 1\n```'))
+
+Find more renderers in `mistune-contrib`_.
+
+Block Level
+~~~~~~~~~~~
+
+Here is a list of block level renderer API::
+
+    block_code(code, language=None)
+    block_quote(text)
+    block_html(html)
+    header(text, level, raw=None)
+    hrule()
+    list(body, ordered=True)
+    list_item(text)
+    paragraph(text)
+    table(header, body)
+    table_row(content)
+    table_cell(content, **flags)
+
+The *flags* tells you whether it is header with ``flags['header']``. And it
+also tells you the align with ``flags['align']``.
+
+
+Span Level
+~~~~~~~~~~
+
+Here is a list of span level renderer API::
+
+    autolink(link, is_email=False)
+    codespan(text)
+    double_emphasis(text)
+    emphasis(text)
+    image(src, title, alt_text)
+    linebreak()
+    newline()
+    link(link, title, content)
+    strikethrough(text)
+    text(text)
+    inline_html(text)
+
+Footnotes
+~~~~~~~~~
+
+Here is a list of renderers related to footnotes::
+
+    footnote_ref(key, index)
+    footnote_item(key, text)
+    footnotes(text)
+
+Lexers
+------
+
+Sometimes you want to add your own rules to Markdown, such as GitHub Wiki
+links. You can't achieve this goal with renderers. You will need to deal
+with the lexers, it would be a little difficult for the first time.
+
+We will take an example for GitHub Wiki links: ``[[Page 2|Page 2]]``.
+It is an inline grammar, which requires custom ``InlineGrammar`` and
+``InlineLexer``:
+
+.. code:: python
+
+    import copy,re
+    from mistune import Renderer, InlineGrammar, InlineLexer
+
+    class WikiLinkRenderer(Renderer):
+        def wiki_link(self, alt, link):
+            return '<a href="%s">%s</a>' % (link, alt)
+
+    class WikiLinkInlineLexer(InlineLexer):
+        def enable_wiki_link(self):
+            # add wiki_link rules
+            self.rules.wiki_link = re.compile(
+                r'\[\['                   # [[
+                r'([\s\S]+?\|[\s\S]+?)'   # Page 2|Page 2
+                r'\]\](?!\])'             # ]]
+            )
+
+            # Add wiki_link parser to default rules
+            # you can insert it some place you like
+            # but place matters, maybe 3 is not good
+            self.default_rules.insert(3, 'wiki_link')
+
+        def output_wiki_link(self, m):
+            text = m.group(1)
+            alt, link = text.split('|')
+            # you can create an custom render
+            # you can also return the html if you like
+            return self.renderer.wiki_link(alt, link)
+
+You should pass the inline lexer to ``Markdown`` parser:
+
+.. code:: python
+
+    renderer = WikiLinkRenderer()
+    inline = WikiLinkInlineLexer(renderer)
+    # enable the feature
+    inline.enable_wiki_link()
+    markdown = Markdown(renderer, inline=inline)
+    markdown('[[Link Text|Wiki Link]]')
+
+It is the same with block level lexer. It would take a while to understand
+the whole mechanism. But you won't do the trick a lot.
+
+
+Contribution & Extensions
+-------------------------
+
+Mistune itself doesn't accept any extension. It will always be a simple one
+file script.
+
+If you want to add features, you can head over to `mistune-contrib`_.
+
+Here are some extensions already in `mistune-contrib`_:
+
+* Math/MathJax features
+* Highlight Code Renderer
+* TOC table of content features
+* MultiMarkdown Metadata parser
+
+Get inspired with the contrib repository.
