-## Contributing
+# 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.
+Hi there! We're thrilled that you'd like to contribute to this project. Your help is essential for keeping it great. The majority of contributions won't need to touch any Ruby code at all.
 
-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.
+## Adding a language
 
-### My code is detected as the wrong language
+We try only to add languages once they have some usage on GitHub. In most cases we prefer that languages be in use in hundreds of repositories before supporting them in Linguist.
 
-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. If you can, try to reproduce the highlighting problem in the text editor that the grammar is designed for (TextMate, Sublime Text, or Atom) and include that information in your bug report.
-
-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. You can test grammars using [Lightshow](https://lightshow.githubapp.com).
-
-Once the bug has been fixed upstream, please let us know and we'll pick it up for GitHub.

 In addition, if your new language defines an extension that's already listed in [`languages.yml`][languages] (such as `.foo`) then sometimes a few more steps will need to be taken:
 
-0. Make sure that example `.foo` files are present in the [samples directory][samples] for each language that uses `.foo`. 
+0. Make sure that example `.foo` files are present in the [samples directory][samples] for each language that uses `.foo`.
 0. Test the performance of the Bayesian classifier with a relatively large number (1000s) of sample `.foo` files. (ping @arfon or @bkeepers to help with this) to ensure we're not misclassifying files.
 0. If the Bayesian classifier does a bad job with the sample `.foo` files then a [heuristic](https://github.com/github/linguist/blob/master/lib/linguist/heuristics.rb) may need to be written to help.
 
 Remember, the goal here is to try and avoid false positives!
 
-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.
+## Fixing a misclassified language
+
+Most languages are detected by their file extension defined in [languages.yml][languages].  For disambiguating between files with common extensions, linguist applies some [heuristics](/lib/linguist/heuristics.rb) and a [statistical classifier](lib/linguist/classifier.rb). This process can help differentiate between, for example, `.h` files which could be either C, C++, or Obj-C.
+
+Misclassifications can often be solved by either adding a new filename or extension for the language or adding more [samples][samples] to make the classifier smarter.
+
+## Fixing syntax highlighting
+
+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][languages] is mapped to its corresponding TM `scope`. This scope will be used when picking up a grammar for highlighting.
+
+Assuming your code is being detected as the right language, in most cases this is due to a bug in the language grammar rather than a bug in Linguist.

 # Linguist
 
-We use this library at GitHub to detect blob languages, ignore binary files, suppress generated files in diffs, and generate language breakdown graphs.

-Tips for filing issues and creating pull requests can be found in [`CONTRIBUTING.md`](/CONTRIBUTING.md).
+This library is used on GitHub.com to detect blob languages, ignore binary or vendored files, suppress generated files in diffs, and generate language breakdown graphs.
 
-## Features
+See [Troubleshooting](#troubleshooting) and [`CONTRIBUTING.md`](/CONTRIBUTING.md) before filing an issue or creating a pull request.
 
-### Language detection
+## Troubleshooting
 
-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).
+### My repository is detected as the wrong language
 
-Most languages are detected by their file extension. For disambiguating between files with common extensions, we first apply some common-sense heuristics to pick out obvious languages. After that, we use a
-[statistical
-classifier](https://github.com/github/linguist/blob/master/lib/linguist/classifier.rb).
-This process can help us tell the difference between, for example, `.h` files which could be either C, C++, or Obj-C.

-```ruby
+The Language stats bar is built by aggregating the languages of each file in that repository. If it is reporting a language that you don't expect:
 
-Linguist::FileBlob.new("lib/linguist.rb").language.name #=> "Ruby"
+0. Click on the name of the language in the stats bar to see a list of the files that are identified as that language.
+0. If you see files that you didn't write, consider moving the files into one of the [paths for vendored  code](https://github.com/github/linguist/blob/master/lib/linguist/vendor.yml), or use the [manual overrides](#overrides) feature to ignore them.
+0. If the files are being misclassified, search for [open issues][issues] to see if anyone else has already reported the issue. Any information you an add, especially links to public repositories, is helpful.
+0. If there are no reported issues of this misclassification, [open an issue][new-issue] and include a link to the repository or a sample of the code that is being misclassified.
 
-Linguist::FileBlob.new("bin/linguist").language.name #=> "Ruby"
+## Overrides
+
+Linguist supports a number of different custom overrides strategies for language definitions and vendored paths.
+
+### Using gitattributes
+
+Add a `.gitattributes` file to your project and use standard git-style path matchers for the files you want to override to set `linguist-documentation`, `linguist-language`, and `linguist-vendored`. `.gitattributes` will be used to determine language statistics, but will not be used to syntax highlight files. To manually set syntax highlighting, use [Vim or Emacs modelines](#using-emacs-and-vim-modelines).
+
+```
+$ cat .gitattributes
+*.rb linguist-language=Java
 ```
 
-See [lib/linguist/language.rb](https://github.com/github/linguist/blob/master/lib/linguist/language.rb) and [lib/linguist/languages.yml](https://github.com/github/linguist/blob/master/lib/linguist/languages.yml).
+Checking code you didn't write, such as JavaScript libraries, into your git repo is a common practice, but this often inflates your project's language stats and may even cause your project to be labeled as another language. 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. Vendored files are also hidden by default in diffs on github.com.
 
-### Syntax Highlighting
+Use the `linguist-vendored` attribute to vendor or un-vendor paths.
 
-Syntax highlighting in GitHub is performed using TextMate-compatible grammars. These are the same grammars that TextMate, Sublime Text and Atom use.
+```
+$ cat .gitattributes
+special-vendored-path/* linguist-vendored
+jquery.js linguist-vendored=false
+```
 
-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**.
+Similar to vendored files, Linguist excludes documentation files from your project's language stats. (Unlike vendored files, documentation files are displayed in diffs on github.com.) [lib/linguist/documentation.yml](lib/linguist/documentation.yml) lists common documentation paths and excludes them from the language statistics for your repository.
 
-### Stats
+Use the `linguist-documentation` attribute to mark or unmark paths as documentation.
 
-The Language stats bar that you see on every repository is built by aggregating the languages of each file in that repository. The top language in the graph determines the project's primary language.
+```
+$ cat .gitattributes
+project-docs/* linguist-documentation
+docs/formatter.rb linguist-documentation=false
+```
 
-The repository stats API, accessed through `#languages`, can be used on a directory:
+### Using Emacs and Vim modelines
 
-***API UPDATE***
+Alternatively, you can use Vim and Emacs style modelines to set the language for a single file. Modelines can be placed anywhere within a file and are respected when determining how to syntax-highlight a file on GitHub.com
 
-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`.
+```
+Vim
+vim: set filetype=prolog:
+vim: set ft=cpp:
 
+Emacs

+```
+
+## Usage
+
+Install the gem:

-#### Ignore vendored files
-
-Checking other code into your git repo is a common practice. But this often inflates your project's language stats and may even cause your project to be labeled as another language. We are able to identify some of these files and directories and exclude them.
-
-```ruby
-Linguist::FileBlob.new("vendor/plugins/foo.rb").vendored? # => true
+Ruby:
+Gemfile
+Rakefile
+bin/linguist
+github-linguist.gemspec
+lib/linguist.rb
+…
 ```
 
-See [Linguist::BlobHelper#vendored?](https://github.com/github/linguist/blob/master/lib/linguist/blob_helper.rb) and [lib/linguist/vendor.yml](https://github.com/github/linguist/blob/master/lib/linguist/vendor.yml).
+## Contributing
 
-#### Generated file detection
+Please check out our [contributing guidelines](CONTRIBUTING.md).
 
-Not all plain text files are true source files. Generated files like minified js and compiled CoffeeScript can be detected and excluded from language stats. As an extra bonus, these files are suppressed in diffs.
-
-```ruby
-Linguist::FileBlob.new("underscore.min.js").generated? # => true
-```
-
-See [Linguist::Generated#generated?](https://github.com/github/linguist/blob/master/lib/linguist/generated.rb).
-
-## 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.

-*.rb linguist-language=Java

-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
-```
-
-## Installation
-
-Github.com is usually running the latest version of the `github-linguist` gem that is released on [RubyGems.org](http://rubygems.org/gems/github-linguist).
-
-But for development you are going to want to checkout out the source. To get it, clone the repo and run [Bundler](http://gembundler.com/) to install its dependencies.
-
-    git clone https://github.com/github/linguist.git
-    cd linguist/
-    script/bootstrap
-
-To run the tests:
-
-    bundle exec rake test
-
-### 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`:
-
-```
-Perl:
-  type: programming
-  ace_mode: perl
-  color: "#0298c3"
-  extensions:
-  - .pl
-  - .PL
-  - .perl
-  - .ph
-  - .plx
-  - .pm
-  - .pod
-  - .psgi
-  interpreters:
-  - perl
-```
-Any of the extensions defined are valid but the first in this array should be the most popular.
-
-### Testing
-
-Sometimes getting the tests running can be too much work, especially if you don't have much Ruby experience. It's okay: be lazy and let our build bot [Travis](http://travis-ci.org/#!/github/linguist) run the tests for you. Just open a pull request and the bot will start cranking away.

+Speaks <message> to the room. Use #ignore <name> to not see <name>'s says, poses, and spoofs; use #meow <name> to see <name>'s says with all the words replaced with "meow." Use #third to see your own says in the third person (that is, "Puck says" instead of the normal "You say"). Use #grey to turn off color in others' says and poses.
+
+Say supports a "split" say if you put two consecutive commas in your message. For example, if CobaltBlue typed '"Hello,,how are you?' everyone would see '"Hello," says CobaltBlue, "how are you?"' You can also specify an "ad-hoc" verb by putting a message with your name or '%N' between pairs of commas: '"Hello,,%N welcomes Weiran,,how are you?' would display '"Hello," CobaltBlue welcomes Weiran, "how are you?"'

+ * - As a consequence, as long as a node is referenced from Perl, all its
