!Plugin installation and configuration
!!Installation/Activation/deactivation
Plugin installation and activation is done by simply copying the plugin file(s) to the "plugins" directory.

If you want to deactivate some plugin, you have at least three options:
* Delete plugin file.
* Rename them. LionWiki accepts plugins with specific filename - it must start with "wkp_" and end with ".php".
* Deactivate them in Admin plugin, like [here|./index.php?action=admin-plugins].

!!Plugin configuration
Plugins are basically PHP classes with some member variables -- some of these member variables are configuration options. So if you want to change e.g. password in Admin plugin, open plugins/wkp_Admin.php in text editor and change $PASSWORD member variable.

!!!Configuration in config.php
Plugins configuration explained above has one serious flaw - when you upgrade your installation to newer version of LionWiki, all settings is lost. '''Since LionWiki 3.1''' it is possible to configure plugins in config.php file:
{{$Admin["PASSWORD"] = sha1("my_password");}}
So, you take a look at the member variable name in the plugin class and use it as a member of an array named after plugin.

!Writing plugins
We have special page for this, see [How to write a plugin|UserGuide: How to write a plugin].
