How to install & configure Connect IQ developer Environment?

Hi there,

where i can find some good dokumentation to install & configure Connect IQ developer Environment?

i need it only to compile a app for my new forerunner 945 because i want a app i used on my old Fenix 5, the developer of the app will send me the source code, because he is to busy to adapt it, now i want to give it a try by myself.

i have a lot of it-experience since 30 years, but not on Connect IQ, so it would be fine to get some good tips here!

is it better to wait for final release of connect iq 3.1, read something that it will come soon on Forerunner 945?

cheers!
