### Using gitattributes
Add a `.gitattributes` file to your project and use standard git-style path matchers for the files you want to override using the `linguist-documentation`, `linguist-language`, `linguist-vendored`, and `linguist-generated` attributes. `.gitattributes` will be used to determine language statistics and will be used to syntax highlight files. You can also manually set syntax highlighting using [Vim or Emacs modelines](#using-emacs-or-vim-modelines).

#### Detectable
Only programming languages are included in the language statistics. Languages of a different type (as defined in [`languages.yml`](/lib/linguist/languages.yml)) are not "detectable" causing them not to be included in the language statistics.
Use the `linguist-detectable` attribute to mark or unmark paths as detectable.

### Using Emacs or Vim modelines
If you do not want to use `.gitattributes` to override the syntax highlighting used on GitHub.com, you can use Vim or 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
