 You should be able to compile on Linux, OSX, or MinGW with something like this (you need SDL, SDL_ttf, and SDL_gfx):
 
 ```
-sudo apt-get install gcc libsdl1.2-dev libsdl-ttf2.0-dev libsdl-gfx1.2-dev
+sudo apt-get install make g++ libsdl1.2-dev libsdl-ttf2.0-dev libsdl-gfx1.2-dev libsdl-mixer1.2-dev libglew-dev
 git clone https://github.com/zenorogue/hyperrogue.git hyperrogue
 cd hyperrogue
 make
 ```
 
-The `mymake` program builds HyperRogue in parts. It takes longer than the method shown above, but when you change something, `mymake` will only recompile the changed file.
+The `mymake` program builds HyperRogue in parts. It takes longer than the method shown above, but it uses significantly less memory during compilation, and when you change something, `mymake` will only recompile the changed file.
 Additionally, it can be easily configured, e.g., to produce an optimized build, or to include addons (see `mymake.cpp` for some example invocations, and `devmods` for some example addons).
