The book/library started in August 2019, so it's a work in progress. This is not a usage book. We're working on a book that simply explains usage. We follow patterns used by https://nikhilm.github.io/uvbook/index.html . You create velocity by slowing down and making sure that you always have understanding of what you are doing (or at a minimum make sure you have an understanding of what you don't understand). Developers get better when they can explain what they know (and this is independent of language or technology). Becoming a great developer takes practice. This book may take several reads before you fully get it. The examples intentionally build upon each other, but may build too quickly for some. Feel free to contact us with questions.
For a more in depth usage guide without a tutorial check out our docs.
