+Exclude plugins from appearing in plugins menu for normal user in WordPress multisite.
+
+== Description ==
+
+WordPress 3.0 multisite allows us only to show or hide all of the plugins from normal user,
+nothing else. If we want to allow all users to use some simple plugins, while hiding the 
+*super* plugins only for Super Admins or VIP users, we have to activate the plugin for all
+network in order to make it work. Or else, we have to make them visible by all.
+
+This is why we need Exclude Plugins. Exclude Plugins will exclude plugins from appearing
+in plugins menu for normal user in WordPress multisite. This way, some plugins (excluded
+plugins) will be available only for Super Admins, while other plugins (included plugins)
+will be available for normal user.
+
+If you're **not** using Network Mode/MultiSite in WordPress 3.0, you definitely **not** needing this plugin.
+Here's [how to activate the multisite option](http://itx.web.id/wordpress/mengaktifkan-opsi-multisite-dalam-wordpress-3-0/).
+
+For questions and bug report, please visit [Exclude Plugins page](http://itx.web.id/wordpress/plugins/exclude-plugins/).
+
+== Installation ==
+
+You can use the built in installer and upgrader, or you can install the plugin manually:
+
+1. Download the plugin
+
+2. Upload and extract the contents of exclude-plugins.zip to wp-content/plugins/ folder. You should get a folder called exclude-plugins.
+
+3. Activate the Plugin in WP-Admin.
+
+4. Goto Super Admin > Options > Menu Settings then enable administration menus for plugins.
