It is by absolute pure coincidence that I found out that you you can begin on the bakery stuff by clicking on the cookie below the coins...
I was sitting here for like 15 minutes "okay, great, first thing costs 100 cookies... how the hell do I even get my 1st cookie, nevermind 100 of them..."
After finding out by chance I went looking at the development log and this WAS apparently written in v0.19, but there should be a note in the game itself too.
