Parts of the manual may be a bit difficult, but I think we're trying to make
it good and understandable for everyone. If you have suggestions I encourage
you to send them in an email, or even better as a documentation patch.

Yes and yes. You can add it as a service in your config.scm and then stop and
start it when needed. Or you can run it as a package like you describe here.

Defining packages and services is next level (it's not very difficult, but
not something you should need for regular systems). Look at the sections
under "System Configuration" sepcifically the pages under Services.
