Assign a project to a class
You can assign any individual Codio project to a class.
From the Classes area, click on your class to open it.
Click on the Units tab, centre left of your screen.
Click on the blue plus sign, top left of the page, and choose Add Project.
Select the project you want to assign.
You will show the following screen. In most cases, you would select Use project’s stack. However, if you have installed any components other that those in the project’s stack or made changes outside the code workspace then select the Create new stack option.
