Suppose I’ll dump this here, guide on:
-Device ordering (make lots of trit)
-RCCT (make even more trit)
-And recipes for atmos bombs 
Not a place I recommend new atmos techs start, but might be useful if you have even a little experience with atmos
Also I take no credit in making this website, I did nothing to contribute to it and just wanted to shed some light on it
