1. Move all XF files into a subdirectory
-- Backup all files to a local drive
-- Create the directory /community
-- Upload files from local to /community [leave the files in the root for now]
-- Change settings in configuration files and then /community/admin (options)
-- Make sure everything is working
2. Move files off the root into /community-backup. Verify you did not disrupt /community installation
3. Install WordPress in root so that these are off the root
-- /wp-admin
-- /wp-content
-- /wp-includes
-- run the install program. It is best to have WordPress in one database and XF in another database.
-- verify that WordPress runs properly
www.yourdomain.com
-- adjust .htaccess in root and /community if necessary
4. Install a bridge (optional).
5. Create a hyperlink between WP and XF.
6. Work on WP theme and XF theme so that they match
