You know you should be grateful for everyday. Why not use your favorite blog platform to help you in this.
How in the world do we get this to go. The best way is to use the reposity, and let it do the installer for you.
If you don't want that route (for whatever reason) you will need to manually upload it to the /wp-content/plugins directory, and unzip the file.
Once that is done: 1. Activate the plugin through the 'Plugins' menu in WordPress 1. This plugin has it's own settings page. 1. Go to the settings page, and update the options that you want, mainly what kind of text would you care for. 1. Go, start documenting what you are grateful for.
