+Liminix is pre-1.0. We are still finding new and better ways to do things,
+and there is no attempt to maintain backward compatibility with the old
+ways. This will change when it settles down.
+
+In general: development mostly happens on the `main` branch, which is
+therefore not guaranteed to build or to work on every commit. For the
+latest functioning version, see [the CI system](https://build.liminix.org/jobset/liminix/build) and pick a
+revision with all jobs green.

+  2e50368, especially if they reference things under pkgs.liminix,
+  they will need updating. Look at changes to examples/rotuer.nix
+  for guidance
+
+* the same is intermittently true for examples/{extensino,arhcive}.nix
+  where I've updated rotuer and not updated them to match.
