RedBot Library comes up as Invalid: HELP HELP HELP!!!!!!!!!

I have downloaded the RedBot Library from, but when I try to upload the zip file, it gives me…

Specified folder/zip file does not contain a valid library

I don’t know what to do and I need to get this to work for a student competition. PLEASE HELP as soon as possible.

RedBot-master (1).zip (583 KB)

You might have to install the library manually.

Unzip the file and go to Redbot-master/Arduino/libraries

Which files would I need to manually upload if I only want to make the motors turn for a certain period of time? It only needs to move in a straight line for a period of time. Sorry if I sound clueless, I am a high school student who is just trying to get a car to work. Help is GREATLY appreciated.

You have to learn to start reading the tutorials.
