Hello, I'm interesting in contributing to Drill. I've downloaded the source code and am trying to understand the architecture and where all the pieces fit. I tried going back in time to the initial git commits, so that I could understand how things came to be, but it's still a pretty big codebase. I wanted to know if there are any other guides or advice, apart from the ones on the Drill website, on understanding the structure of the source code better? (I've been through the design documentation)
Also, is it possible to get an invite to Slack? Thanks, Raahul
