So, I wrote my own application which is hosted on Google app engine., and can be accessed on URL like this: http://myapp.appspot.com/ - where "myapp" is the name/id of my application.
I want the app to be accessible on subdomain I don't own (myapp.somedomain.com), and want to give admin of somedomain.com info he needs to set it up.
There is an awful lot of info about that, but after hours of googling I'm still not sure what I need to tell the admin. There's a lot of talk about having to sign up for Google Apps which is supposedly free but I can only find that it has either trial period or costs $50/year, and about setting a CNAME. Can someone give me simple instructions - what do I tell my admin (apart from http://myapp.appspot.com/ URL), and what do I need to do in my Google app engine control panel?
