We are going to deploy the new yiiframework.com website on March 23, 2018 from 8:00 to 12:00 UTC.
Website and Yii documentation will not be available in this time frame. Check the news for more details.
This tutorial will guide you through the process of creating a yii application using Cloud9. We will use a git workspace to enable version control and also show how to link the Cloud9 workspace to GitHub.
