This guide will explain how to install a WordPress plugin.
Don’t worry it’s simple, all you need is an FTP client like Filezilla. This guide assumes you are using WordPress version 2.6 or above and you know how to use FTP software.
Download your plugin from somewhere like WordPress.
Unzip your plugin and drag it to the wp-content/plugins folder in your FTP program.
Now your plugin will be in the active section. You will be able to change the settings of most plugins by going to the menu section set out in the plugin instructions.
