 NixOS configuration
 ===================
 
-My NixOS config. Some manual steps required before the first run!
+My NixOS configuration! It configures most of the packages I require
+on my systems, sets up Emacs the way I need and does a bunch of other
+interesting things.
 
-Make sure submodules are cloned: `git submodule update --init`.
+In contrast with earlier versions of this configuration, the Nix
+channel versions are now pinned in Nix (see the beginning of
+[packages.nix][]).
 
-Set up the unstable NixOS channel:
+Machine-local configuration is kept in files with the naming scheme
+`$hostname-configuration.nix` and **must** be symlinked to
+`local-configuration.nix` before the first configuration run.
 
-```
-nix-channel --add http://nixos.org/channels/nixos-unstable nixos-unstable
-nix-channel --update
-```
+I'm publishing this repository (and my [emacs configuration][]) as a
+convenience for myself, but also as a resource that people looking for
+example Nix or Emacs configurations can browse through.
 
-Symlink local machine configuration to `/etc/nixos/local-configuration.nix`.
+Feel free to ping me with any questions you might have.
