Plugins are tools that extend the functionality of your WordPress site. You can add features like eCommerce (WooCommerce), SEO optimization (Yoast SEO), contact forms, and security enhancements without any coding knowledge.

To use a plugin, simply:

Go to your WordPress dashboard.
Navigate to Plugins > Add New.
Search for the desired plugin and click Install and then Activate.
Tip: Be cautious of too many plugins, as they may slow down your site or cause compatibility issues.
