Need help, completely lost!

Hi

Im totally new with docker hub and completely lost!!! I all ready download the docker hub for mac but have no idea where to write the code to start working. Do I need to download another program to be able to write the code and connect it to the docker program that I install in mac?

Is it possible to write the code somewhere online and be able to connect it to the docker hub account?

Any help I will sincerly appreciate!!!
