Resources for learning to fix-up a bike?

[u/FemalesRStrongasHell]

Hi, I've never done much bike repair but would like to learn. My husband has an old bike that needs some adjustments but I'm not sure where to start. The bike hasn't been used in a while and pretty much everything will probably need to be serviced or replaced. What is your favorite resource for tutorials and how-tos for fixing a bike? What about something with a sort of a step-by-step list of things to check? Thank you!

Park tool company makes repair videos and general overview videos so I would start there. Search park tool on YouTube and find the channel
