WordPress is the most-deployed content management system on the planet. There are a number of reasons that it is so popular: it is easy to use, easy to host, free, and open source. A major driver of its popularity is plugins.

WordPress is extremely extensible. With a plugin, you can add nearly limitless functionality to your site. There are thousands of high-quality free and premium WordPress plugins available. But, sometimes, you need something really custom. Building a WordPress plugin gives you the ability to make exactly the features you need for your site.

If you have a little bit of coding background, or are willing to learn some PHP, building your own WordPress plugins isn't that difficult. To help you out we've collected the best tutorials on the subject, along with links to helpful resources and important tools for plugin developers.
