WordPress plugin

A plugin is a self-contained unit of source code which "plugs in" to some larger computer program.

Plugins allow for the modification of existing features, and the addition of new features.

Programs that support plugins, such as WordPress, are said to have a plugin architecture.

Many plugins are available for free. Other plugins are commercial products, commonly with a free starter version, and a pay version which unlocks more features.

Authoring plugins

Authoring new plugins requires some knowledge of PHP, and specific knowledge about the plugin architecture. Many tutorials and examples are available on the web to help developers acquire the necessary knowledge.
