Obviously, this number is going to go up over time, but right now, it's pretty bite-sized and (hopefully) easy enough to follow. Certainly not of the scale of something like GHC, which clocks in at [over 135k LOC](http://www.aosabook.org/en/ghc.html)!
One brief note for orientation. Because of the split between `shared/` and `node/`, a module like `Unison.Term` (in `shared/`), which has the basic type and instances for JSON encoding/decoding, has a counterpart in `shared/`, `Unison.Term.Extra` with things like _binary_ serialization or hashing of `Unison.Term` values. Logically, it would be nice to put all functionality in the `Unison.Term` module, but binary serialization and hashing code isn't needed by the editor and we don't want to accidentally compile those libraries and code to JS or rely on tree-shaking to hopefully trim it out. Other `.Extra` modules are analogous.

Now, where to begin? Everyone learns differently. You might prefer to read the code 'inside out' (or perhaps 'bottom up'), starting from the core language syntax tree and typechecker, then expanding out to where these get exposed to the outside world. If this route sounds appealing, here's a reasonable path:
