This extension takes data from Northeastern's online schedule website and adds classes to Classes calendar as events. To use, go to the myNortheastern portal and click schedule, select the semester you want to add, and click the extension's icon in the top right of chrome. It will ask you to sign into the account you want to add the events to. Once you've signed in, there will be a new calendar called "Classes", with all of your classes added to it!
