-## Releasing
+Linguist is maintained with :heart: by:
+
+- @arfon (GitHub Staff)
+- @larsbrinkhoff
+- @pchaigno
+
+As Linguist is a production dependency for GitHub we have a couple of workflow restrictions:
+
+- Anyone with commit rights can merge Pull Requests provided that there is a :+1: from a GitHub member of staff
+- Releases are performed by GitHub staff so we can ensure GitHub.com always stays up to date with the latest release of Linguist and there are no regressions in production.

+
+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 added bonus, unlike vendored and documentation files, these files are suppressed in diffs.

 ### Using Emacs or Vim modelines

 Alternatively, 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
