+Build
+-----
+The data files are kept separately on a subversion repository. Grab them with:
+
+    svn co svn://mutantstargoat.com/datadirs/voxelburg data
+
+Alternatively grab a release tarball if available.
+
+To build the game,
+[setup the devkitarm environment](https://devkitpro.org/wiki/Getting_Started),
+and type `make`. Only the basic cross-toolchain, libc and C runtime are required
+from devkitarm. No other libraries are used.
+
+The tools which are part of the build process might have more requirements:
+
+  - **pngdump**: libpng and zlib.
