+# Arithmatex <small>MathJax</small>
+
+[Arithmatex][] integrates [MathJax][] with Markdown and is included in the
+[PyMdown Extensions][] package. It parses block-style and inline equations
+written in TeX markup and outputs them in mathematical notation.
+
+## Installation
+
+Make sure that the PyMdown Extensions package [is installed][] and add the
+following lines to your `mkdocs.yml`:
+
+``` yaml
+markdown_extensions:
+  - pymdownx.arithmatex
+```
+
+The MathJax runtime is automatically included if the extension is enabled, so
+there is no need for extra JavaScript.
+
+## Usage
+
+MathJax searches for `:::tex $$...$$` (blocks) and `:::tex $...$` (inline)
+equations, parses their contents and renders them in mathematical notation.
+See [this thread][] on StackExchange for a short introduction and quick
+reference on how to write equations in TeX syntax.
+
+### Blocks
+
+Blocks are enclosed in `:::tex $$...$$` which are placed on separate lines.
+
+Example:
+
+``` tex
+$$
+\frac{n!}{k!(n-k)!} = \binom{n}{k}
+$$
+```
+
+Result:
+
+$$
+\frac{n!}{k!(n-k)!} = \binom{n}{k}
+$$
+
+### Inline
+
+Inline equations need to be enclosed in `:::tex $...$`:
+
+Example:
+
+``` tex
+Lorem ipsum dolor sit amet: $p(x|y) = \frac{p(y|x)p(x)}{p(y)}$
+```
+
+Result:
+
+Lorem ipsum dolor sit amet: $p(x|y) = \frac{p(y|x)p(x)}{p(y)}$

+The PyMdown Extensions package can be installed with the following command:

 ``` sh
 pip install pymdown-extensions
 ```

-## Usage
+## Extensions

-### Improvements on existing Markdown
+### GitHub Flavored Markdown

- BetterEm
- SuperFences
- MagicLink
+Most of the extensions included in the PyMdown Extensions package try to bring
+the Markdown experience closer to GitHub Flavored Markdown (GFM):
+
+- [BetterEm][] improves the handling of emphasis markup (**bold** and *italic*)
+  within Markdown by providing a more sophisticated parser for better detecting
+  start and end tokens. Read the documentation for usage notes.
+
+- [MagicLink][] detects links in Markdown and auto-generates the necessary
+  markup, so no special syntax is required. It auto-links HTTP(S) and FTP
+  links, as well as references to email addresses.
+
+- [GitHub Emoji][] adds the ability to insert emojis, which does not only
+  include the :octocat: emojis, but also a :shit:-load of emojis that we use in
+  our daily lives. See the [Emoji Cheat Sheet][] for a list of all available
+  emojis. Happy scrolling :tada:
+
+- [SuperFences][] provides the ability to nest code blocks under blockquotes,
+  lists and other block elements, which the [Fenced Code Blocks][] extension
+  from the standard Markdown library doesn't parse correctly.
+
+- [Tasklist][] adds support for styled checkbox lists. This is useful for
+  keeping track of tasks and showing what has been done and has yet to be done.
+  The usage of this extension is documented [here][].
+
+- [Tilde][] provides an easy way to ~~strike through~~ cross out text.
+  The portion of text that should be erased must be enclosed in two tildes
+  `~~...~~`, and the extension will take care of the rest.
+
+The PyMdown Extensions package adds a shorthand to enable all of the included
+extensions that provide the GFM experience. However, usage of the shorthand is
+discouraged, because some extensions are not supported, as the Material theme
+uses the counterparts included in the standard Markdown library.
+
+To enable all extensions add the following lines to your `mkdocs.yml`:
+
+``` yaml
+markdown_extensions:
+  - pymdownx.betterem
+  - pymdownx.githubemoji
+  - pymdownx.magiclink
+  - pymdownx.superfences
+  - pymdownx.tasklist(custom_checkbox=true)
+  - pymdownx.tilde
+```
+
+### Syntactic Sugar
+
+There are three other extensions that add further syntactic sugar:
+
+- [Caret][] is the sister extension of [Tilde][] and makes it possible to
+  highlight ^^inserted text^^. The portion of text that should be marked as
+  added must be enclosed in two carets `^^...^^`, the extension will do the
+  rest.
+
+- [Mark][] add the ability to ==mark text==.
