 # ynl-c
-Standalone copy of generated YNL C lib
+
+Standalone copy of generated YNL C lib.
+
+Development happens in the Linux kernel:
+
+https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next.git/tree/tools/net/ynl/
+
+This repo contains just the C parts, excluding all Python and
+scripts, even the code generator which generated the code.
+
+Basic intro:
+
+https://docs.kernel.org/next/userspace-api/netlink/intro-specs.html#ynl-lib
+
+Using the library
+=================
+
+Building the library generates an archive for static linking called ``ynl.a``.
