+## 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. 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.
+
+### 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.

 ### Language detection

 ### 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**.

+
 ```ruby
-project = Linguist::Repository.from_directory(".")

 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

+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`:

+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.
 
 Here's our current build status, which is hopefully green: [![Build Status](https://secure.travis-ci.org/github/linguist.png?branch=master)](http://travis-ci.org/github/linguist)

+// Distributions Primer
+//
+// This primer demonstrates uses of some of Chapel's standard
+// distributions.  To use these distributions in a Chapel program,
+// the respective module must be used:
+//
+use BlockDist, CyclicDist, BlockCycDist, ReplicatedDist;
+use DimensionalDist2D, ReplicatedDim, BlockCycDim;
+
+//
+// For each distribution, we'll create a distributed domain and array
+// and then initialize it just to give a brief flavor of how the
+// distribution maps across locales.  Running this example on 6
+// locales does a nice job of illustrating the distribution
+// characteristics.
+//
+// All of these distributions support options to map to a different
+// virtual locale grid than the one used by default (a
+// multidimensional factoring of the built-in Locales array), as well
+// as to control the amount of parallelism used in data parallel
+// loops.  See the Standard Distributions chapter of the language spec
+// for more details.
+//
+
+//
+// Make the program size configurable from the command line.
+//
+config const n = 8;
+
+//
+// Declare a 2-dimensional domain Space that we will later use to
+// initialize the distributed domains.
+//
+const Space = {1..n, 1..n};
+
+//
+// The Block distribution distributes a bounding box from
+// n-dimensional space across the target locale array viewed as an
+// n-dimensional virtual locale grid.  The bounding box is blocked
+// into roughly equal portions across the locales.  Note that domains
+// declared over a Block distribution can also store indices outside
+// of the bounding box; the bounding box is merely used to compute
+// the blocking of space.
+//
+// In this example, we declare a 2-dimensional Block-distributed
+// domain BlockSpace and a Block-distributed array BA declared over
+// the domain.
+//
+const BlockSpace = Space dmapped Block(boundingBox=Space);
+var BA: [BlockSpace] int;

+// Most of Chapel's standard distributions support an optional
+// targetLocales argument that permits you to pass in your own
+// array of locales to be targeted.  In general, the targetLocales
+// argument should match the rank of the distribution.  So for
+// example, to map a Block to a [numLocales x 1] view of the
+// locale set, one could do something like this:
+
+//
+// We start by creating our own array of the locale values.  Here
+// we use the standard array reshape function for convenience,
+// but more generally, this array could be accessed/assigned like any
+// other.

+// The DimensionalDist2D distribution lets us build a 2D distribution
+// as a composition of specifiers for individual dimensions.
+// Under such a "dimensional" distribution each dimension is handled
+// independently of the other.
+//
+// The dimension specifiers are similar to the corresponding multi-dimensional
+// distributions in constructor arguments and index-to-locale mapping rules.
+// However, instead of an array of locales, a specifier constructor
+// accepts just the number of locales that the indices in the corresponding
+// dimension will be distributed across.
+//
+// The DimensionalDist2D constructor requires:
+// * an [0..nl1-1, 0..nl2-1] array of locales, where
+//   nl1 and nl2 are the number of locales in each dimension, and
+// * two dimension specifiers, created for nl1 and nl2 locale counts, resp.
+//
+// Presently, the following dimension specifiers are available
+// (shown here with their constructor arguments):
+//
+// * ReplicatedDim(numLocales)
+// * BlockDim(numLocales, boundingBoxLow, boundingBoxHigh)
+// * BlockCyclicDim(lowIdx, blockSize, numLocales)
+//
+
+//
+// The following example creates a dimensional distribution that
+// replicates over 2 locales (when available) in the first dimemsion
+// and distributes using block-cyclic distribution in the second dimension.
+// The example computes nl1 and nl2 and reshapes MyLocales correspondingly.
+//
+
+var (nl1, nl2) = if numLocales == 1 then (1, 1) else (2, numLocales/2);
