  3. Copy YiiStrap.
  4. Change configuration.
  5. Use Gii: Automated Code Generation.
  6. Create CRUD using Gii

Install Yii

  1. Download the latest Yii Framework from here: http://www.yiiframework.com/download/
  2. Unzip it into your htdocs or www or public_html folder. Basically unzip it into a browse-able location.
