How to use notmuch on several devices

[moonmaillist at firemail.cc]

Hi @ll

This is the first time I am using a mailing list ever. So please have 
patients with me, if I do stuff wrong.

I really want to use my mailboxes on several devices, but because 
notmuch doesn't edit emails (at least that's what I've read so far), I 
just wonder, how to keep the inboxes the same/in sync and export/import 
notmuch configuration and how to use it on a new device? Would a git 
repository be a good idea, which includes the notmuch database and all 
emails?
