-By supplying `TARGET=(rustc target triple)` as an additional argument, you can change the architecture that gila will be compiled & run for. The default is `x86_64-unknown-none`.
+To change the target gila will be compiled or run for, supply `TARGET={valid-rustc-targettriple}` either as an argument to `make` or as an environment variable. The default is `x86_64-unknown-none`.
 
-The default limine BIOS file search directory is `/usr/share/limine`. You can change this by supplying a path (no trailing slash) like so: `LIMINE-DIR=/home/user/Downloads/limine`.
+To change the search path for limine's binaries, supply `LIMINEDIR=/some/valid/path/no/trailing/slash` either as an argument to `make` or as an environment variable. The default is `/usr/share/limine`.
