+Plugin Directory Configuration
+==============================
+
+To install, update and remove plugins from the user interface, you must have those requirements:
+
+- The plugin directory must be writeable by the web server user
+- The Zip extension must be available on your server
+- The config parameter `PLUGIN_INSTALLER` must be set at `true`
+
+To disable this feature, change the value of `PLUGIN_INSTALLER` to `false` in your config file.
+You can also change the permissions of the plugin folder on the filesystem.
+
+Only administrators are allowed to install plugins from the user interface.
+
+By default, only plugin listed on Kanboard's website are available.
