As a developer/software engineer, what would you say are the most helpful resources when attempting to learn and use a new system?

If you had to integrate a new SDK into your codebase/application, which one of the following options would you much rather go with?

• documentation
• tutorials
• video tutorials

Same question for learning a new framework (e.g. writing an iOS app, learning Python, integrating the Android SDK, etc.). I'm not referring to becoming an expert, just get to know enough to use a system/language/framework properly.

This is a pretty general question, but I think it's very relevant to anyone who's doing engineering work, since learning how to use new systems quickly is a very important skill to have.

Thank you!
