Where do you go for actual step-by-step instructions?

While the Documentation is very helpful, where do you go for actual step-by-step instructions for implementing a feature. While the Documentation defines the aspects/functions of the software, the Documentation does not explain implementation of everything; for example, search “Add instrument to parameter sheet”. If you read everything, you can logically figure out the steps through trail and error, normally; however, it would be nice to have actual step-by-step guides. In the end, I’ve had to right my own guides. Have I missed anything, here?
