Installing the CrazyEgg Integration plugin for WordPress is not different than installing any other WordPress plugin. Begin by downloading the installer file. Then simply go to your WordPress administration area (wp-admin), choose the Plugins → Add New menu item on the left side bar, then click on the upload link on the top of the page. Click on Browse, select the plugin ZIP file and then click on Install Now. The next and final necessary step is configuring the plug-in.

Click on Plugins → CrazyEgg Configuration menu item in the left sidebar. In the configuration page,there is only one option, your CrazyEgg account ID. This is your numerical CrazyEgg account ID, consisting exclusively of 8 digits. The easy way to find it is by logging in to your CrazyEgg account and clicking the "What's my code"link:

In the new page, towards the bottom, you will find your Account ID number:

Type this number, including any leading zeros, in the plug-in's configuration field. When you're done click on Update Options. That's all!
