Atelier Source code versioning

Hi

I'm starting work with the Atelier. 

Starting from the point that Eclipse uses local files on the workstation, COS development can be versioned with market tools (For example GIT or Subversion).

I would like to know how the community has worked with code versioning, to create a consistent versioning model.

I initially have the following doubts:

1.  Creation of WorkSpaces and Projects
2.  Merge files
3. Change Branch Functional Development
4. Promotion of Environments: Development -> Homologation -> Production
5. Generating Historical Tags

Thank you all.
