Change the default data installed when setting up WordPress

Question

Is there documentation somewhere on how to change the default data that is entered into the WordPress database when setting up a new database?

I want to change the default category and add a couple others. Change the default post. Set a different theme, activate a couple plugins all by default. All of this to make it easy for setting up multiple sites that are all similar.

Answer 1

See Initialization Script for “Standard” Aspects of a WordPress Website? and my plugin WordPress Basic Settings for details. You may also use a custom install.php but that’s somewhat tricky for multi-site setups.
