The best way to start is to read this document, then join the chat and say hello! We’ll help you from there. It’s also useful to take a look at ARCHITECTURE.md document, which describes how the plugin actually works and at the CONTRIBUTING.md, which contains some useful tips.
By the end of the impl period, we should:
Have the totally ultimate name resolution
Including macro expansion
Have the totally ultimate type inference
Have `unresolved reference` inspection without false-positives(blocked on name resolution, moslty on macros)
Have auto-import quick fix(blocked on `unresolved reference` inspection)
