Good resource for basic company valuation instructions

Embarrassed to say that I’ve forgotten most of my business valuation theory. Can anyone point me to a quick and dirty valuation walk through on the web? I’d scour my CFA textbooks but I don’t have too much time. Any help would be appreciated!

Nice!

Check out Aswath Damodaran’s YouTube channel. He has series of valuation videos, maybe 25 in total, 10-15min each covering equity valuation at a high level.
