+# Building MegaZeux for PS2
+
+NOTE: Only tested on Linux.
+
+## Preparation
+
+You need to build or install the [ps2dev](https://github.com/ps2dev/ps2dev) toolchain.
+
+The toolchain comes with all MegaZeux dependencies pre-installed.
+
+## Configuration
+
+See CONFIG.PS2 for an optimal `config.sh' configure line. You need
+to ensure PS2DEV is defined and valid.
