Most information is found in git-submodule.sh, although 
Documentation/git-submodule.txt has beginnings of a good documentation.

The basic idea is this:

A subdirectory contains a self-contained project.

Once that project is at a stage you want to have in the superproject, you 
can commit that submodule state, much like a subdirectory.

However, the history can progress in much coarser steps for the 
superproject.  IOW an ideal case for msysgit.git, where we want to have a 
stable version which can be checked out with GitMe.

Also, find more about submodules here:
