-Want to build the Mac OS ROM? Start with a working Docker.
+This repo is **obsolete**. We have ported our Mac OS ROM build system to MPW. Ask about the new CDG5 build system at the MacOS9Lives forum.
 
-```
-make "Mac OS ROM.hqx"
-```
-
-Want to explore the Nanokernel? Builds will assemble a new kernel from the `kernel-disasm.s` file:
-
-```
-make kernel-redisassemble
-```
-
-And to revert to building with the stock nanokernel:
-
-```
-make kernel-revert-to-stock
-```
-
-With QEMU 2.7.0 or later installed:
-
-```
-make test
-```
-
-To hide the kernel log: look for `uncomment to debug` in `boot-script`. To change its colour, look at the very end of your `kernel-disasm.s`.
