 # Nimrod packages
 
-This repository provides a list packages for babel.
+This is a central listing of all packages for babel.
+
+## Adding your own package
+To add your own package, fork this repository, edit packages.json and make
+a pull request.
+
+Packages.json is a simple array of objects. Each package object should have the
+following fields:
+  
+  * name   - The name of the package, this should match the name in the package's
+             babel file.
+  * url    - The url from which to retrieve the package.
+  * method - The method that should be used to retrieve this package. Currently
+             only "git" is supported.
+  * tags   - A list of tags describing this package.
+  * description - A description of this package.
+
+Your packages may be removed if the url stops working. It goes without
+saying that your pull request will not be accepted unless you fill out all of
+the above fields correctly, the package that ``url`` points to must also contain
+a babel file, or else it will be rejected.
