A. Upload Plugin to WordPress
First upload the plugin to WordPress using one of the following methods
Automatic Install (recommended)
Copy the entire wpbook-lite directory into your wordpress plugins folder,
B. Create Facebook App
Set up a New Application at http://www.facebook.com/developers, obtaining an App ID, App Secret and API key. Once you have an app you’ll need to enter the following settings.
Basic Info Section
When you first request the app you’ll be asked for an App Display Name (what users will see the app called) and Namespace (a machine friendly version with no spaces, all lower case, no special characters):
Here is just basic information for your app. You may use the image above (click for full size) to help you fill out the settings if needed. The App ID and App Secret will be provided by Facebook. The contact email is not displayed but users can use it to contact you if they have problems with your app. The app domain should be the domain at which your blog lives.
In the “Choose how your application integrates with Facebook,” click to open the “Website” section:
Here you’ll need to provide the site url, which should be the url of your WordPress install. This is the url users use to hit the main page of your WordPress powered site, whether that is a static front page or your blog listing page. Do NOT including index.php, but including a trailing slash.
Leave the rest unchanged, and save changes.
Note: As of late February 2012, you’ll need to change some advanced Facebook settings if you are creating a new Facebook application.
C. Activate the Plugin
Login to your WordPress Admin and activate the “WPBook” plugin (Dashboard->Plugins->WPBook>Activate).
D. Fill out Basic Plugin Settings
Using the WPBook Lite menu, (Dashboard->Settings->WPBook Lite) fill in the appropriate information including Facebook application secret, API key, and profileID (yours).
After you’ve filled in the required settings, jump to the bottom of the page and hit “save” to save your settings.
