Themes decide how your content is presented on the front end of your WordPress site. Plugins are extensions that quite literally plug in to WordPress to add new features and new functionality. While WordPress is great and powerful out of the box, with plugins, you can make WordPress into so much more. They range from simple, like adding image galleries, to the complex like turning WordPress into a social network.
In the WordPress community, there is a saying that goes around: “there’s a plugin for that”. The downside to plugins is that there are so many of them and many plugins do the exact same thing just in slightly different ways. So, here at YSJ, WordPress websites come with certain pre-installed Plugins available for any sites to use (see below for help with each one).
