Plugins offer a way to extend MusicBee's capabilities through user-created scripts. Unless there are other instructions, plugins are installed by unzipping all files (if necessary) and placing them in the Plugins folder of your MusicBee program directory (C:\Program Files (x86)\MusicBee\Plugins, frequently). They should be automatically activated the next time you start MusicBee, but if they are not, you can enable them through Preferences>Plugins.
To add a plugin to the wiki, make a page for it and include the link [[Category:Plugins]] at the bottom or "Plugins" keyword in the Category box. That will automatically list the page here. Please read Wiki Contributors Guidelines first.
