+## Status
+
+All the functionality is in place to load keymaps. More tests are needed,
+and more polish. The aim is to have this done by the end of 2024.

+## Building
+
+On Linux, cir depends on llvm for BPF code generation. On Fedora you
+need the `llvm-devel` package install and `llvm-dev` on Ubuntu.
