+# New packages
+
+READ THIS FIRST
+
+This module is for official packages in the Plasma Mobile Gear. All
+available packages are listed in `./srcs.nix`, although some are not yet
+packaged in Nixpkgs.
+
+IF YOUR PACKAGE IS NOT LISTED IN `./srcs.nix`, IT DOES NOT GO HERE.
+
+See also `pkgs/applications/kde` as this is what this is based on.
+
+# Updates
+
+1. Update the URL in `./fetch.sh`.
+2. Run `./maintainers/scripts/fetch-kde-qt.sh pkgs/applications/plasma-mobile`
+   from the top of the Nixpkgs tree.
+3. Use `nox-review wip` to check that everything builds.
+4. Commit the changes and open a pull request.
