+***API UPDATE***
+
+Since [Version 3.0.0](https://github.com/github/linguist/releases/tag/v3.0.0) Linguist expects a git repository (in the form of a [Rugged::Repository](https://github.com/libgit2/rugged#repositories)) to be passed when initializing `Linguist::Repository`.
+
+
 ```ruby
-project = Linguist::Repository.from_directory(".")
+require 'rugged'
-project.language.name  #=> "Ruby"
+require 'linguist'
-project.languages      #=> { "Ruby" => 0.98, "Shell" => 0.02 }
+
+repo = Rugged::Repository.new('.')
+project = Linguist::Repository.new(repo, repo.head.target_id)
+project.language       #=> "Ruby"
+project.languages      #=> { "Ruby" => 119387 }
 ```
 
 These stats are also printed out by the `linguist` binary. You can use the
 `--breakdown` flag, and the binary will also output the breakdown of files by language.

+## 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
+```

+    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.
