You have created a blank project. This is really a blank project! This is the only file.

You can add files to your project:

1. Right click on the project tree.
2. In the Project menu.
3. Create files on the command line. Click the "+" button in the Console panel to open a terminal window.

You can perform install software, use the included version control tools, or run scaffolders like rails (if your workspace has it installed). You can change the project type in Project > Configuration.
