WordPress plugins are tools which provide additional functionality to your application. To install a plugin you generally just need to put the plugin file into your ‘wp-content/plugins’ directory. Once a plugin is installed, you may activate it or deactivate it from the Plugins menu in your WP administration.
Generally the Plugin installation is a straight-forward process. In most cases it is enough to upload the plugin under the ‘wp-content/plugins’ directory for the WordPress installation and activate it from the administrator backend.
You can install plugins directly from the admin area. Downlod the plugin to your computer, then log in to your WP admin area and go to Plugins > Add New. Browse to the plugin archive and select it. Then click Install Now and the plugin will be installed shortly.
The removal is also straight-forward in most cases. Simply remove the directory for the plugin you would like to uninstall and it will be automatically deactivated.
Still always bear in mind that not all plugins are easy to install, so always refer to their documentation and installation instructions first.
For your reference and information, two of the following plugins are included with the WordPress core distribution:
- Akismet: Akismet checks your comments against the Akismet web service to see if they look like spam or not. You can review the spam it catches under “Manage” and it automatically deletes old spam after 15 days.
- Hello Dolly: This is not just a plugin, it symbolizes the hope and enthusiasm of an entire generation summed up in two words sung most famously by Louis Armstrong. Hello, Dolly. This is, by the way, the world’s first official WordPress Plugin. When enabled you will randomly see a lyric from “Hello, Dolly” in the upper right of your Administration Panels on every page.
