Managing a private wiki/Adding extensions

Getting the .php file(s)
First, one must download the  files. This can be done in several ways.
 * SVN
 * MediaWiki code is kept in a subversion repository (SVN repo). Download the files using an SVN client to the appropriate location ( usually)


 * Add either a  or   near the bottom of your LocalSettings.php file, and check Special:Version on your wiki to see if the extension is installed properly. See the examples.

Setting up the database

 * Some extensions require database tables - one of the files in the extension folder will be an SQL query to create the table. phpMyAdmin is a useful tool for altering the database.

Troubleshooting

 * If the extension fails to install properly, check the relevant page on MediaWiki.org if there are specialized installation requirements. Some extensions may have dependencies requiring installation of additional software.
