WordPress.org

1. Upload misiek-page-category folder to the /wp-content/plugins/ directory.
2. Activate the plugin through the 'Plugins' menu in WordPress.
3. Manage albums from administration menu..

In order to upgrade to 2.1 version you must reinstall the plugin by simply clicking uninstall and install again

This process should be not necessary if you use auto upgrade. But if something will go wrong please uninstall and the install again.

Uninstallation will not remove your categories created before but just in case please make a backup of your database before any upgrade.
