WordPress’ heart is outlined to maximize resiliency, to increase functionality and minimize code errors. Plugins allow users to customize their sites to their specifications through the functions and features that are offered.
The most common source for WordPress Plugins is the WordPress.org repo but there are a lot of other sources as well. You can easily search the web for these and you will see a list of those that would fit your need.
Aside from being able to get additional plugins there are some that are already included.
One is Akismet, what it does is it checks your comments to see if they look like spam or not. By accessing “Manage” you can review things that it catches as spam. The other one is Hello Dolly, the very first official WordPress Plugin.
With the help of plugins, you can always have your website the way you want it to be.
