HOW to use isaac sdk and isaac sim?

Hello everyone, I am a student and I have just been in contact with ISAAC not long ago. I would like to ask what can I do with ISAAC SDK and ISAAC SIM? What is the specific process? If I have a UR3 robotic arm, what can I do with isaac

The Isaac Sim Omniverse documentation (here) and the Isaac SDK (here) are good starting points.
