All of the help documentation that you see in the Student Documentation section still applies to the GoReact app in Schoology. The only thing that is different is where you log in.
If your instructor is using Schoology, then you cannot access your course directly at goreact.com. Instead, all you need to do is log into Schoology, open your course, and click on an assignment that uses GoReact.

Submitting a video
To submit a video, just click the name of the applicable assignment in Schoology, which will open the GoReact app in Schoology. Then, click the red "Add Video" button to record or upload your video.
