+## Contributing
+
+The majority of contributions won't need to touch any Ruby code at all. The [master language list][languages] is just a YAML configuration file.
+
+Almost all bug fixes or new language additions should come with some additional code samples. Just drop them under [`samples/`][samples] in the correct subdirectory and our test suite will automatically test them. In most cases you shouldn't need to add any new assertions.
+
+### My code is detected as the wrong language
+
+This can usually be solved either by adding a new filename or file name extension to the language's entry in [`languages.yml`][languages] or adding more [samples][samples] for your language to the repository to make Linguist's classifier smarter.
+
+### Syntax highlighting looks wrong
+
+Assuming your code is being detected as the right language (see above), in most cases this is due to a bug in the language grammar rather than a bug in Linguist. [`grammars.yml`][grammars] lists all the grammars we use for syntax highlighting on github.com. Find the one corresponding to your code's programming language and submit a bug report upstream.
+
+You can also try to fix the bug yourself and submit a Pull Request. [This piece from TextMate's documentation](http://manual.macromates.com/en/language_grammars) offers a good introduction on how to work with TextMate-compatible grammars.
+
+Once the bug has been fixed upstream, please let us know and we'll pick it up for GitHub.
+
+### I want to add support for the `X` programming language
+
+Great! You'll need to:
+
+0. Add an entry for your language to [`languages.yml`][languages].
+0. Add a grammar for your language to [`grammars.yml`][grammars] by running `script/download-grammars --add URL`. Please only add grammars that have a license that permits redistribution.
+0. Add samples for your language to the [samples directory][samples].
+
+We try only to add languages once they have some usage on GitHub, so please note in-the-wild usage examples in your pull request. In most cases we prefer that languages already be in use in hundreds of repositories before supporting them in Linguist.

 ## Features
 
 ### Language detection
 
-Linguist defines a list of all languages known to GitHub in a [yaml file](https://github.com/github/linguist/blob/master/lib/linguist/languages.yml). In order for a file to be highlighted, a language and a lexer must be defined there.

 ### Syntax Highlighting
 
-The actual syntax highlighting is handled by our Pygments wrapper, [pygments.rb](https://github.com/tmm1/pygments.rb). It also provides a [Lexer abstraction](https://github.com/tmm1/pygments.rb/blob/master/lib/pygments/lexer.rb) that determines which highlighter should be used on a file.
+Syntax highlighting in GitHub is performed using TextMate-compatible grammars. These are the same grammars that TextMate, Sublime Text and Atom use.
+
+Every language in `languages.yml` is mapped to its corresponding TM `scope`. This scope will be used when picking up a grammar for highlighting. **When adding a new language to Linguist, please add its corresponding scope too (assuming there's an existing TextMate bundle, Sublime Text package, or Atom package) so syntax highlighting works for it**.

+## Overrides
+
+Linguist supports custom overrides for language definitions and vendored paths. Add a `.gitattributes` file to your project using the keys `linguist-language` and `linguist-vendored` with the standard git-style path matchers for the files you want to override.
+
+Please note that the overrides currently only affect the language statistics for a repository and not the syntax-highlighting of files.
+
+```
+$ cat .gitattributes
+*.rb linguist-language=Java
+
+$ linguist --breakdown
+100.00% Java
+
+Java:
+ruby_file.rb
+```
+
+By default, Linguist treats all of the paths defined in [lib/linguist/vendor.yml](https://github.com/github/linguist/blob/master/lib/linguist/vendor.yml) as vendored and therefore doesn't include them in the language statistics for a repository. Use the `linguist-vendored` attribute to vendor or un-vendor paths.
+
+```
+$ cat .gitattributes
+special-vendored-path/* linguist-vendored
+jquery.js linguist-vendored=false
+```

 ### A note on language extensions
 
 Linguist has a number of methods available to it for identifying the language of a particular file. The initial lookup is based upon the extension of the file, possible file extensions are defined in an array called `extensions`. Take a look at this example for example for `Perl`:

+    OBTW The positions of the spheres are essentially
+         stored in a 2-D array. This differs from Kensler's
+         version where he used bit flags to store the
+         positions in a compressed and quickly accessed
+         manner. Unfortunately for us, bit operations
+         in LOLCODE were too slow for this to be a tenable
+         solution.
