Installing via WordPress
Sugar Calendar is installed just like any other plugin in WordPress.
Once you have downloaded the .zip file from your purchase receipt, log into your WordPress site and click on Plugins > Add New. At the top of the screen is a button titled Upload Plugin. Click this.
You will now be asked to select a file from your computer. Navigate to where you saved the .zip file from your purchase receipt and select it.
Once installed, click Activate Plugin.
You will now have a menu item labeled Events near the middle of the admin menu in WordPress.
