It's best really to have a conjuration skill of 90 so's you can start the Conjuration Ritual Spell quest you get from Phinis Gestor. This is a quick guide I made for myself really listing all the recipes for the atronach forge located in the Winterhold Midden, to save me some time trying to figure out what the daedric lettering on the notes mean, but if anyone else gets any use out of it then great.
