 ## Building
 
-Run `make js` to bundle all the builtins. The output is placed in `src/js/out/{modules,functions}/`, where these files are loaded dynamically by `bun-debug` (an exact filepath is inlined into the binary pointing at where you cloned bun, so moving the binary to another machine may not work). In a release build, these get minified and inlined into the binary (Please commit those generated headers).
