 ### Makefile
 A Makefile is provided, which requires the `make` command. Simply clone the repository and run `make all` to grab all necessary dependencies for go/python/node, compile everything and place the executable and app data inside `build/`. You can optionally compress the executable by running `make compress` after.
+* By default, `make all` will embed the program's assets inside the binary. If you want jfa-go to use external assets, use `make all-external` instead, and they will be placed next to the executable in `data/`.
 
 * If you get an error from npm regarding esbuild, this is because a precompiled binary for your system's architecture isn't available on npm. run `make all GOESBUILD=on` instead to have it compiled instead.
