Upload the full directory into your wp-content/plugins directory
Activate the plugin at the plugin administration page
Open the plugin configuration page, which is located under Options -> Best Posts Summary and configure the initial settings. The plugin will not generate new summary posts until you select a posting frequency and click on Save Settings at the bottom.
The plugin will automatically create a new post and publish it at the begining of the next month, next week, or next day depending on the frequency you chose, so theres nothing more to do :)
