Considering purchasing Litchi for my CrystalSky and Mavic Mini 1. Are they compatible?

I am super interested in purchasing this app, however, I have some questions concerning Litchi

I have a DJI Mavic Mini 1st generation and a 5.5-inch DJI CrystalSky.

Will Litchi work on this?

If so, What are the step-by-step instructions that I need to do in order to install the app, attach it to my controller, and get this up and running on my CrystalSky?

Thank you very much.

Welcome @John_Lembeck ,
This will help answer most, if not all of your questions.

Thank you. And this will work with the Mavic Mini 1?

Litchi is compatible with: Mini 2, Mini SE, Air 2S, Mavic Mini 1,…
