 ## Building on Linux
 
 - Ensure python3 is installed.
-- Ensure the SDL2 and GLEW libraries are installed if you're building the test program (on Ubuntu: libsdl2-dev, libglew-dev)
+- Ensure the SDL2 and GLEW libraries are installed if you're building the test program (on Ubuntu: libsdl2-dev, libglew-dev).
 - Run `make` to build. If you want to link musl libc instead of glibc run `LIBSM64_MUSL=1 make` instead.
 - To run the test program you'll need a SM64 US ROM in the root of the repository with the name `baserom.us.z64`.
 
 ## Building on Windows
 - [Follow steps 1-4 for setting up MSYS2 MinGW 64 here](https://github.com/sm64-port/sm64-port#windows), but replace the repository URL with `https://github.com/libsm64/libsm64.git`

 ## Make targets (all platforms)
 
 - `make lib`: (Default) Build the `dist` directory, containing the shared object or DLL and public-facing header.
 - `make test`: Builds the library `dist` directory as well as the test program.
 - `make run`: Build and run the SDL+OpenGL test program.
