+### GITHUB SYNTAX HIGHLIGHTING
+
+As an extra feature, you can syntax highlight a file from your repository, allowing
+you keep some of your sample code in the main repository. The code-snippet is
+updated when the wiki is rebuilt. You include github code like this:
+
+    ```html:github/gollum/master/test/file_view/1_file.txt```
+
+This will make the builder look at the **github user**, in the **gollum project**,
+in the **master branch**, at path **test/file_view/1_file.txt**. It will be
+rewritten to:
+
+    ```html
+    <ol class="tree">
+      <li class="file"><a href="0">0</a></li>
+    </ol>
+    ```
+
+Which will be parsed as HTML code during the Pygments run, and thereby coloured 
+appropriately.
 
 ## MATHEMATICAL EQUATIONS
 
-Page files may contain mathematic equations in TeX syntax that will be nicely
-typeset into the expected output. A block-style equation is delimited by `\[`
-and `\]`. For example:
+Start gollum with the `--mathjax` flag. Read more about [MathJax](http://docs.mathjax.org/en/latest/index.html) on the web. Gollum uses the `TeX-AMS-MML_HTMLorMML` config with the `autoload-all` extension.
 
-    \[ P(E) = {n \choose k} p^k (1-p)^{ n-k} \]
+Inline math:
 
-Inline equations are delimited by `\(` and `\)`. These equations will appear
-inline with regular text. For example:
+- $2^2$
+- `\\(2^2\\)`
 
-    The Pythagorean theorem is \( a^2 + b^2 = c^2 \).
+Display math:
 
-Gollum uses [MathJax](http://www.mathjax.org/) to convert the TeX syntax into
-output suitable for display in web browsers.
+- $$2^2$$
+- [2^2]
 
+## SEQUENCE DIAGRAMS
+
+You may imbed sequence diagrams into your wiki page (rendered by
+[WebSequenceDiagrams](http://www.websequencediagrams.com) by using the
+following syntax:
+
+    {{{{{{ blue-modern

+## WINDOWS FILENAME VALIDATION
+Note that filenames on windows must not contain any of the following characters `\ / : * ? " < > |`. See [this support article](http://support.microsoft.com/kb/177506) for details.
+
+## CONFIG FILE
+
+Gollum optionally takes a `--config file`. See [config.rb](https://github.com/github/gollum/blob/master/config.rb) for an example.
+
+## CUSTOM CSS
+
+The `--css` flag will inject `custom.css` from the root of your git repository into each page. `custom.css` must be commited to git or you will get a 302 redirect to the create page. Here's an example of floating the sidebar to the left.
