If you are viewing this in github you can view the book version of it HERE
This is an attempt to document most of the important stuff around how to use the library, it is recommended that you follow the order of the TOC, however if you are not using the gitbook version then just look at the summary.md file and follow that order.
The flow is generally:
Stuff you should ideally know before using the framework
About the framework and how to use it
The bits which make up the framework and how to use them
Making larger applications with the framework
How the underlying architecture fits together
How you can extend the framework and use plugins
How to use the framework in a more performance oriented manner
Feel free to add to the docs or come on the Discord Channel if you need help!
