+# Updating
+
+To update the list of packages from ELPA,
+
+1. Run `./update-elpa-devel`.
+2. Check for evaluation errors:
+     # "../../../../../" points to the default.nix from root of Nixpkgs tree
+     env NIXPKGS_ALLOW_BROKEN=1 nix-instantiate ../../../../../ -A emacs.pkgs.elpaDevelPackages
+3. Run `git commit -m "elpa-devel-packages $(date -Idate)" -- elpa-devel-generated.nix`
+
+## Update from overlay
+
+Alternatively, run the following command:
+
+./update-from-overlay
+
+It will update both melpa and elpa packages using
+https://github.com/nix-community/emacs-overlay. It's almost instantenous and
+formats commits for you.
