+## Conventions
+
+* Filenames should **not** include version number and be **lowercase**
+* Javascript & Css files should be minified, If the library doesn't already provide a minified version, our preferred minifier is [UglifyJS](http://marijnhaverbeke.nl/uglifyjs "UglifyJS")
+* If updating an existing library, try to keep consistant with the existing structure
