First you have to choose which branch of PWB you want to use:
 * Core (formerly called "rewrite"), which is better for use on WMF projects (like Wikipedia), but be aware that not all scripts have been migrated to this branch yet, so maybe you can't run some scripts (see the compatibility list)
 * Compat (formerly called "trunk"): It's old and slow and dirty, but you can use it so much more easier in non-WMF projects (for example for wikis without API support) and most of the scripts exist in this branch. If you used PWB before the migration, you probably used this branch
