+# Updates
+
+Before a major version update, make a copy of this directory. (We like to
+keep the old version around for a short time after major updates.) Add a
+top-level attribute to `top-level/all-packages.nix`.
+
+1. Update the URL in `pkgs/development/libraries/qt-5/$VERSION/fetch.sh`.
+2. From the top of the Nixpkgs tree, run
+   `./maintainers/scripts/fetch-kde-qt.sh > pkgs/development/libraries/qt-5/$VERSION/srcs.nix`.
+3. Update `qtCompatVersion` below if the minor version number changes.
+4. Check that the new packages build correctly.
+5. Commit the changes and open a pull request.
