Browse Happy is site that identifies the latest versions of modern web browsers in an effort to raise the awareness of the options available. Its goal is to promote use of the most up-to-date browsers for their better security, support, features, performance, and implementation of web standards.
The official repository is actually located at https://meta.svn.wordpress.org/sites/trunk/browsehappy.com/, with an associated component on the Meta Trac system for bug reports.
That said, the Git repository is an active peer to the meta.svn repository and all changes (ideally) would be committed here first (and if not, synced back over ASAP).
- Simply clone this repository into the themes directory (typically
wp-content/themes/) of a standard test WordPress install. If you need to know how to do that, see Installing WordPress.
- Activate the theme.
- Make and test your recommended changes in a branch and make a pull request to the Github repository.
