Learn How to Customize Your WordPress Theme for BuddyPress with the BP Template Pack Plugin
If you’re looking for some BuddyPress documentation on customizing your theme, the Theme Development section of the BuddyPress codex is a good source of information for starting out. Topics range from modifying the BuddyPress admin bar to making your theme BuddyPress compatible.
One of the recommended ways to bring BuddyPress into your regular WordPress theme is to use the BP Template Pack plugin. The BuddyPress codex now has a handy section called BP Template Pack Walkthrough – Easy Level that will take you through the process step-by-step.
The guide is packed full of illustrations to help you get the correct HTML structure, templates and CSS in place for displaying the BuddyPress elements in an attractive way. Firebug will definitely be your friend in this process. I wish this guide had been there the first time I had to do this, and I assure you that this is one of the most complete references available for making the most of the BP Template Pack plugin.
