Extensions are plug-ins to eZ Publish, providing additional custom functionality. Various extensions are available for eZ Publish. All of them require the same basic steps for an installation. This chapter will show how to perform the following:

1. Extract the compressed archive containing the extension
2. Activate the extension

Some extensions might require further action to make them fully functional, e.g. creating new database tables, adding certain content classes to eZ Publish, etc. Such additional measures are explained in the documentation for each extension.

As outlined before, this section deals with the basic steps only. For demonstration purposes, the installation will be exemplified by an imaginary extension called "ezfoo".
