Check out this video: [DConf 2016 Day 2 Keynote: Spelunking D 
Compiler Internals -- Walter 
Bright](https://www.youtube.com/watch?v=bNJhtKPugSQ)
Just browsing [dmd's source 
code](https://github.com/dlang/dmd/tree/master/src/dmd#readme) 
and watching [dmd's Pull Request 
queue](https://github.com/dlang/dmd/pulls) is a good way to get 
familiar with the code and see what a bug fix looks like. Try to 
start with something small, like error message improvements or 
[refactorings listed in the contributing 
guide](https://github.com/dlang/dmd/blob/master/CONTRIBUTING.md#dmd-best-practices). If you have any questions along the way, just ask them.
