A guide how to do room correction and use it in Roon

New house, new system! The measurement is about what I was expecting, given speaker placement (photo in this post)…

I auto-generated 20-800hZ, and then manually added 2 more points at 2.5kHz and 15.8kHz. First listen just now was pretty great. In my old system I did a lot of fiddling around before I got to something I really enjoyed, so any tips would be appreciated.
