-# Build Instructions
+# Prebuilt Binary
+
+See the releases tab.
 
-## Linux
+On linux, you will need to install the SDL2 package from your package maintainer.

-distributor. [official page](http://libsdl.org/download-2.0.php)

+
+# Build Instructions
 
-```bash
+## On Linux
+
+Install the [libSDL2](http://libsdl.org/download-2.0.php) runtime and SDL2 
+development packages from your package distributor.  On Fedora, this 
+is the `SDL2` and `SDL2-devel` packages.
+
+```
 git clone --recurse-submodules https://git.topost.net/alistair/space_game.git
-cd space_game
-make
 ```
 
-By default it is built using debug flags.
+### For Linux
+
+```
+make clean
+make target=linux
+```
+
+### For Windows
+
+You have to have mingw and the mingw libsdl library (I think).
+
+Run setup.sh to download the SDL2 static libraries and `SDL2.dll`.
+
+```
+./setup.sh
+make clean
+make target=windows
+```
+
+### With debug flags
 
+Append `debug=true` to the make command.
