I completed the tutorial stuff the other day took me a while since it was very enjoyable and started on my first base which I spent like 2-5 hours building this. I have the 5:6 ratio of red:green, but for some reason belts aren't being built fast enough, which is probably because I might need more belt makers since I assumed 2 belt per automation, so I'd need 1:2 automation for belt to inserter. How should I expand so I can research faster, since it's only at most 50% active, and is there a more efficient layout better for expanding for when I unlock the other potion(s)?
