What you are learning
Apishelf is turning on only the Google APIs your app actually needs. The teaching focus is APIs and Services (API Library, enabled APIs, service usage).
Work in order. Early parts set vocabulary and environment; later parts assume the earlier checkpoints.
How to use these lessons
Read the goal, open the matching GitHub folder, complete the lab or exercises, then return for the explanation. If a command fails, check you are in the numbered folder first.
