 ## Compiling
 
-* Run `make rom` to build the ROM. The ROM will be written to `build/ntsc-final/pd.z64`.
+* Run `make -j` to build the ROM. The ROM will be written to `build/ntsc-final/pd.z64`.
 
 ## How do I know the built files are matching?
 
-Run `make` followed by `make test`. If `make test` produces no output then all compiled segments are matching.

 You can also md5sum your base ROM with the built ROM and check they have the same hash: `md5sum pd.ntsc-final.z64 build/ntsc-final/pd.z64`.
