What is a WordPress plugin?
Plugins offer extra features and custom functions to self-hosted WordPress sites.

Tips for Selecting WordPress Plugins
You should only install plugins that you feel are essential to running your site. The more plugins you install, the slower your site will load. You should also install plugins that are current and show an active support response from the developer. On the right column of every plugin introduction page, you’ll see a description for the plugin ratings, date of most recent update, and WordPress release compatibility.
Creating a Template Backup
Prior to installing or updating plugins, you should always backup your WordPress site. If your site doesn’t function properly, you likely installed a plugin that isn’t compatible with your template code or other plugins running on your site.
