## Checking in a project

You can and should checkin your files multiple times. Even if you are not done with your project, you should always checkin your project before you leave your computer. The process of checking in a project is very similar to checking out a project.

In order to check in a project select Ambient > Checkin Project (alternatively you may press Ctrl + Alt + S). You will see all projects in your workspace that are ready to be checked in. Select one project and click Finish.
The process will run in the background. You will be informed if your files have not been checked in successfully.

# Undo

With each checkin, your project files will be tagged with the date. This lets you come back later and undo any incorrect changes you later made. Please be very careful with this function as it will remove your latest code and only let you use the code that you decided to revert to. Use the Undo button on the Ambient toolbar for this functionality.
