 ## Build Instructions
 
-Coming soon, but I do know it builds on OSX and Linux. I primarily work on Windows.
+Pre-requisites:
+
+* Meson -- which need Python
+* C++ Compiler -- Tested with Clang and G++
+* GNU make -- For the convenience Makefile
+
+Windows instructions

+
+cd roguish
+# ignore the errors the first time
+./scripts/reset_build.ps1
+
+# first compile takes a while
+make
+
+# will play a sound and open windows
