To start developing with WPDK framework, first of all you have to install WPDK in your WordPress environment. Please follow these simple rules to accomplish this task.

1. Verify the system requirements:
   • Wordpress 3.4 or higher (last stable version is highly suggested) - Note: WordPress MU is not yet supported.
   • PHP version 5.2.4 or greater
   • MySQL version 5.0 or greater
   • We suggest to update your browser always at its last version, because WPDK uses javascript language to accomplish some tasks.
2. Download the zip of WPDK framework from official GitHub repository clicking here. This is the official stable (production) branch of the framework. If you want to download the framework from other branches of this repo, please remember that their source code is still experimental, and then it is not ready to be used in any production environment.
3. Unzip the framework. You will have its root directory named wpdk-production
4. Copy the entire wpdk-production folder in the wp-content/plugins directory of your WordPress environment.

Done. WPDK framework is installed in your environment.

Please note that you won't see WPDK framework in your WordPress plugins dashboard, because WPDK does not need to be activated. Once installed, WPDK is immediately ready and available.
