Module Baselines

Hello,

I am using version 5.0.1.

I am trying to figure out a way to do versioning on DOORS. Is building a module baseline the only way I can do versioning? Also, if creating a module baseline is indeed the only way, would I need to create a new module baseline every single time I make a change to my requirements document? If this is so, do you have any suggestions on how to manage all these versions that I would be creating?

Lastly, how do I compare the changes I have made on previous modules?

Thank you in advance,
