Installation of the Content API module is like any other Drupal module:

1. Download Content API
2. Place the files in your Drupal site's /sites/all/modules directory. This will create the module in the “contentapi” folder.
3. Download and install prerequisite modules:
   • Services 3.x
   • REST Server (included in Services)
   • Chaos Tools
   • Autoload
4. Navigate to the module installation page (Administer -> Site Building -> Modules) and check the box by “Content API” under “Services - Resources”. It is assumed you have all the prerequisite modules installed
5. Click the “Save Configuration” button at the bottom of the page to install the module.
