+Installation & Usage
 -------------------------------------------------
 
 1. Download and extract the files to a subfolder such as `tagging-tools` inside the `qa-plugins` folder of your Q2A installation. Since the Github repo is updated regularly, a stable versioned package is also provided, e.g. `Q2A-Tagging-Tools-1.5.zip`

    WARNING: if you have a lot of questions on your site, converting all the old questions will take a long time. Version 1.5 now uses AJAX to edit a few posts at a time, however, it may still cause high MySQL and Apache CPU usage. It's recommended that you add tag synonyms a handful at a time to avoid too much overhead.
 
 6. The option "Prevent new users from creating new tags" adds a Javascript barrier preventing low-rep users from creating new tags. Currently there is no way to replicate this on the server side without hacking the core, but that will rarely be a problem.
