+## SYNTAX
+
+Gollum supports a variety of formats and extensions (Markdown, MediaWiki, Textile, …).
+On top of these formats Gollum lets you insert headers, footers, links, image, math and more.
+
+Check out the [Gollum Wiki](https://github.com/gollum/gollum/wiki) for all of Gollum's formats and syntactic options.

 Note that the gollum server will not run on Windows because of [an issue](https://github.com/rtomayko/posix-spawn/issues/9) with posix-spawn (which is used by Grit).
 
-## REPO STRUCTURE
-
-A Gollum repository's contents are designed to be human editable. Page content
-is written in `page files` and may be organized into directories any way you
-choose. Special footers can be created in `footer files`. Other content
-(images, PDFs, etc) may also be present and organized in the same way.
-
-## PAGE FILES
-
-Page files may be written in any format supported by
-[GitHub-Markup](http://github.com/github/markup) (except roff). By default,
-Gollum recognizes the following extensions:
-
-* ASCIIDoc: .asciidoc
-* Creole: .creole
-* Markdown: .markdown, .mdown, .mkdn, .mkd, .md
-* Org Mode: .org
-* Pod: .pod
-* RDoc: .rdoc
-* ReStructuredText: .rest.txt, .rst.txt, .rest, .rst
-* Textile: .textile
-* MediaWiki: .mediawiki, .wiki
-
-You may also register your own extensions and parsers:
-
-```ruby
-Gollum::Markup.register(:angry, "Angry") do |content|
-  content.upcase
-end
-```
-
-Gollum detects the page file format via the extension, so files must have one
-of the default or registered extensions in order to be converted.
-
-Page file names may contain any printable UTF-8 character except space
-(U+0020) and forward slash (U+002F). If you commit a page file with any of
-these characters in the name it will not be accessible via the web interface.
-
-Even though page files may be placed in any directory, there is still only a
-single namespace for page names, so all page files should have globally unique
-names regardless of where they are located in the repository.
-
-The special page file `Home.ext` (where the extension is one of the supported
-formats) will be used as the entrance page to your wiki. If it is missing, an
-automatically generated table of contents will be shown instead.
-
-## SIDEBAR FILES
-
-Sidebar files allow you to add a simple sidebar to your wiki. Sidebar files
-are named `_Sidebar.ext` where the extension is one of the supported formats.
-Sidebars affect all pages in their directory and any subdirectories that do not
-have a sidebar file of their own.
-
-## HEADER FILES
-
-Header files allow you to add a simple header to your wiki. Header files must
-be named `_Header.ext` where the extension is one of the supported formats.
-Like sidebars, headers affect all pages in their directory and any
-subdirectories that do not have a header file of their own.
-
-## FOOTER FILES
-
-Footer files allow you to add a simple footer to your wiki. Footer files must
-be named `_Footer.ext` where the extension is one of the supported formats.
-Like sidebars, footers affect all pages in their directory and any
-subdirectories that do not have a footer file of their own.
-
-## HTML SANITIZATION
-
-For security and compatibility reasons Gollum wikis may not contain custom CSS
-or JavaScript. These tags will be stripped from the converted HTML. See
-`docs/sanitization.md` for more details on what tags and attributes are
-allowed.
-
-## TITLES
-
-The first defined `h1` will override the default header on a page. There are
-two ways to set a page title. The metadata syntax:
-
-    <!-- --- title: New Title -->
-
-The first `h1` tag can be set to always override the page title, without
-needing to use the metadata syntax. Start gollum with the `--h1-title` flag.
-
-## BRACKET TAGS
-
-A variety of Gollum tags use a double bracket syntax. For example:
-
-    [[Link]]
-
-Some tags will accept attributes which are separated by pipe symbols. For
-example:
-
-    [[Link|Page Title]]
-
-In all cases, the first thing in the link is what is displayed on the page.
-So, if the tag is an internal wiki link, the first thing in the tag will be
-the link text displayed on the page. If the tag is an embedded image, the
-first thing in the tag will be a path to an image file. Use this trick to
-easily remember which order things should appear in tags.
-
-Some formats, such as MediaWiki, support the opposite syntax:
-
-    [[Page Title|Link]]
-
-## PAGE LINKS
-
-To link to another Gollum wiki page, use the Gollum Page Link Tag.
-
-    [[Frodo Baggins]]
-
-The above tag will create a link to the corresponding page file named
-`Frodo-Baggins.ext` where `ext` may be any of the allowed extension types. The
-conversion is as follows:
-
-1. Replace any spaces (U+0020) with dashes (U+002D)
-2. Replace any slashes (U+002F) with dashes (U+002D)
-
-If you'd like the link text to be something that doesn't map directly to the
-page name, you can specify the actual page name after a pipe:
-
-    [[Frodo|Frodo Baggins]]
-
-The above tag will link to `Frodo-Baggins.ext` using "Frodo" as the link text.
-
-The page file may exist anywhere in the directory structure of the repository.
-Gollum does a breadth first search and uses the first match that it finds.
-
-Here are a few more examples:
-
-    [[J. R. R. Tolkien]] -> J.-R.-R.-Tolkien.ext
-    [[Movies / The Hobbit]] -> Movies---The-Hobbit.ext
-    [[モルドール]] -> モルドール.ext
-
-
-## EXTERNAL LINKS
-
-As a convenience, simple external links can be placed within brackets and they
-will be linked to the given URL with the URL as the link text. For example:
-
-    [[http://example.com]]
-
-External links must begin with either "http://" or "https://". If you need
-something more flexible, you can resort to the link syntax in the page's
-underlying markup format.
-
-
-## ABSOLUTE VS. RELATIVE VS. EXTERNAL PATH
-
-For Gollum tags that operate on static files (images, PDFs, etc), the paths
-may be referenced as either relative, absolute, or external. Relative paths
-point to a static file relative to the page file within the directory
-structure of the Gollum repo (even though after conversion, all page files
-appear to be top level). These paths are NOT prefixed with a slash. For
-example:
-
-    gollum.pdf
-    docs/diagram.png
-
-Absolute paths point to a static file relative to the Gollum repo's
-root, regardless of where the page file is stored within the directory
-structure. These paths ARE prefixed with a slash. For example:
-
-    /pdfs/gollum.pdf
-    /docs/diagram.png
-
-External paths are full URLs. An external path must begin with either
-"http://" or "https://". For example:
-
-    http://example.com/pdfs/gollum.pdf
-    http://example.com/images/diagram.png
-
-All of the examples in this README use relative paths, but you may use
-whatever works best in your situation.
-
-
-## FILE LINKS
-
-To link to static files that are contained in the Gollum repository you should
-use the Gollum File Link Tag.
-
-    [[Gollum|gollum.pdf]]
-
-The first part of the tag is the link text. The path to the file appears after
-the pipe.
-
-
-## IMAGES
-
-To display images that are contained in the Gollum repository you should use
-the Gollum Image Tag. This will display the actual image on the page.
-
-    [[gollum.png]]
-
-In addition to the simple format, there are a variety of options that you
-can specify between pipe delimiters.
-
-To specify alt text, use the `alt=` option. Default is no alt text.
-
-    [[gollum.png|alt=Gollum and his precious wiki]]
-
-To place the image in a frame, use the `frame` option. When combined with the
-`alt=` option, the alt text will be used as a caption as well. Default is no
-frame.
-
-    [[gollum.png|frame|alt=Gollum and his precious wiki]]
-
-To specify the alignment of the image on the page, use the `align=` option.
-Possible values are `left`, `center`, and `right`. Default is `left`.
-
-    [[gollum.png|align=center]]
-
-To float an image so that text flows around it, use the `float` option. When
-`float` is specified, only `left` and `right` are valid `align` options.
-Default is not floating. When floating is activated but no alignment is
-specified, default alignment is `left`.
-
-    [[gollum.png|float]]
-
-By default text will fill up all the space around the image. To control how
-much should show up use this tag to stop and start a new block so that
-additional content doesn't fill in.
-
-    [[_]]
-
-To specify a max-width, use the `width=` option. Units must be specified in
-either `px` or `em`.
-
-    [[gollum.png|width=400px]]
-
-To specify a max-height, use the `height=` option. Units must be specified in
-either `px` or `em`.
-
-    [[gollum.png|height=300px]]
-
-Any of these options may be composed together by simply separating them with
-pipes.
-
-
-## ESCAPING GOLLUM TAGS
-
-If you need the literal text of a wiki or static link to show up in your final
-wiki page, simply preface the link with a single quote (like in LISP):
-
-    '[[Page Link]]
-    '[[File Link|file.pdf]]
-    '[[image.jpg]]
-
-This is useful for writing about the link syntax in your wiki pages.
-
-## TABLE OF CONTENTS
-
-Gollum has a special tag to insert a table of contents (new in v2.1)
-
-    [[_TOC_]]
-
-This tag is case sensitive, use all upper case.  The TOC tag can be inserted
-into the `_Header`, `_Footer` or `_Sidebar` files too.
-
-There is also a wiki option `:universal_toc` which will display a
-table of contents at the top of all your wiki pages if it is enabled.
-The `:universal_toc` is not enabled by default.  To set the option,
-add the option to the `:wiki_options` hash before starting the
-frontend app:
-
-```ruby
-Precious::App.set(:wiki_options, {:universal_toc => true})
-```
-
-## SYNTAX HIGHLIGHTING
-
-In page files you can get automatic syntax highlighting for a wide range of
-languages (courtesy of [Pygments](http://pygments.org/) - must install
-separately) by using the following syntax:
-
-    ```ruby
-      def foo
-        puts 'bar'
-      end
-    ```
-
-The block must start with three backticks, at the beginning of a line or
-indented with any number of spaces or tabs.
-After that comes the name of the language that is contained by the
-block. The language must be one of the `short name` lexer strings supported by
-Pygments. See the [list of lexers](http://pygments.org/docs/lexers/) for valid
-options.
-
-The block contents should be indented at the same level than the opening backticks.
-If the block contents are indented with an additional two spaces or one tab,
-then that whitespace will be ignored (this makes the blocks easier to read in plaintext).
-
-The block must end with three backticks indented at the same level than the opening
-backticks.
-
-### 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/gollum/master/test/file_view/1_file.txt```
-
-This will make the builder look at the **gollum 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
-
-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.
-
-Inline math:
-
-- \\(2^2\\)
-
-Display math:
-
-- $$2^2$$
-- \\[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
-      alice->bob: Test
-      bob->alice: Test response
-    }}}}}}
-
-You can replace the string "blue-modern" with any supported style.
-
-## API DOCUMENTATION
-
-The [Gollum API](https://github.com/gollum/gollum-lib/) allows you to retrieve
-raw or formatted wiki content from a Git repository, write new content to the
-repository, and collect various meta data about the wiki as a whole.
-
-Initialize the `Gollum::Repo` object:
-
-```ruby
-# Require rubygems if necessary
-require 'rubygems'
-
-# Require the Gollum library
-require 'gollum-lib'
-
-# Create a new Gollum::Wiki object by initializing it with the path to the
-# Git repository.
-wiki = Gollum::Wiki.new("my-gollum-repo.git")
-# => <Gollum::Wiki>
-```
-
-By default, internal wiki links are all absolute from the root. To specify a different
-base path, you can specify the `:base_path` option:
-
-```ruby
-wiki = Gollum::Wiki.new("my-gollum-repo.git", :base_path => "/wiki")
-```
-
-Note that base_path just modifies the links. To map gollum to a non-root location:
-
-- Use the gollum binary: `gollum path/to/wiki --base-path mywiki`
-- Define config.ru with `map`. See [#532](https://github.com/gollum/gollum/issues/532) for an example.
-
-> :base_path     - String base path for all Wiki links.
->
-> The String base path to prefix to internal links. For example, when set
-> to "/wiki", the page "Hobbit" will be linked as "/wiki/Hobbit". Defaults
-> to "/".
-
-Get the latest version of the given human or canonical page name:
-
-```ruby
-page = wiki.page('page-name')

-
-```ruby
-wiki.file('asset.js', '5ec521178e0eec4dc39741a8978a2ba6616d0f0a')
-```
-
-Get an in-memory Page preview (useful for generating previews for web
-interfaces):
-
-```ruby
-preview = wiki.preview_page("My Page", "# Contents", :markdown)
-preview.formatted_data
-# => "<h1>Contents</h1>"
-```
-
-Methods that write to the repository require a Hash of commit data that takes
-the following form:
-
-```ruby
-commit = { :message => 'commit message',
-           :name => 'Tom Preston-Werner',
-           :email => 'tom@github.com' }
-```
-
-Write a new version of a page (the file will be created if it does not already
-exist) and commit the change. The file will be written at the repo root.
-
-```ruby
-wiki.write_page('Page Name', :markdown, 'Page contents', commit)
-```
-
-Update an existing page. If the format is different than the page's current
-format, the file name will be changed to reflect the new format.
-
-```ruby
-page = wiki.page('Page Name')
-wiki.update_page(page, page.name, page.format, 'Page contents', commit)
-```
-
-To delete a page and commit the change:
-
-```ruby
-wiki.delete_page(page, commit)
