+This is the OpenWrt SDK. It contains a stripped-down version of
+the buildroot. You can use it to test/develop packages without
+having to compile your own toolchain or any of the libraries
+included with OpenWrt.
+
+To use it, just put your buildroot-compatible package directory
+in the subdir 'package/' and run 'make' from this directory.
