kotlinlang

Hi everyone, i want to implement/contribute <https://discuss.kotlinlang.org/t/kotlin-to-support-package-protected-visibility>
Would be great if someone familiar with the kotlinc could give me pointers where to start, what potential issues i need to be aware of and test for... any reading material that could help me kickstart working on the compiler would be awesome. I already have the project building fine, now going trough some of the tests in compiler.
