General advice: be it a web app or low level cryptography library in rust or a unity game. Always run it first! And I mean run from the code you downloaded and built (not prebuilt binaries). Then try to debug it. Also read every bit of documentation you can get your hands on. Remember many will be built idiomatically, for example if tailwind is being used your life is easier if you read the tailwind docs and come back to the repo rather than try to figure it out yourself. The more idioms being used you know, the easier it is to understand, and the less surface area of unknowns there are.
