+# GNOME Shell extensions
+
+All extensions are packaged automatically. They can be found in the `pkgs.gnomeXYExtensions` for XY being a GNOME version. The package names are the extension’s UUID, which can be a bit unwieldy to use. `pkgs.gnomeExtensions` is a set of manually curated extensions that match the current `gnome.gnome-shell` versions. Their name is human-friendly, compared to the other extensions sets. Some of its extensions are manually packaged.
+
+## Automatically packaged extensions
+
+The actual packages are created by `buildGnomeExtension.nix`, provided the correct arguments are fed into it. The important extension data is stored in `extensions.json`, one line/item per extension. That file is generated by running `update-extensions.py`. Furthermore, the automatic generated names are dumped in `collisions.json` for manual inspection. `extensionRenames.nix` contains new names for all extensions that collide.
+
+### Extensions updates
+
+For everyday updates,
+
+1. Run `update-extensions.py`.
+2. Update `extensionRenames.nix` according to the comment at the top.
+
+For GNOME updates,
+
+1. Add a new `gnomeXYExtensions` set
+2. Remove old ones for GNOME versions we don’t want to support any more
+3. Update `supported_versions` in `./update-extensions.py` and re-run it
+4. Change `gnomeExtensions` to the new version
+5. Update `./extensionsRenames.nix` accordingly
+6. Update `all-packages.nix` accordingly (grep for `gnomeExtensions`)
+
+## Manually packaged extensions
+
+Manually packaged extensions overwrite some of the automatically packaged ones in `pkgs.gnomeExtensions`. They are listed in `manuallyPackaged.nix`, every extension has its own sub-folder.

+            "link" follows the following schema: "/extension/$number/$string/"
+                   The number is monotonically increasing and unique to every extension.
+                   The string is usually derived from the extension name (but shortened, kebab-cased and URL friendly).
+                   It may diverge from the actual name.
+            The keys of "shell_version_map" are GNOME Shell version numbers.
