+# Changes to the framework top-level
+
+## Overview
+
+When the framework profile was created, there weren't other models of laptop available by the
+company. Now there are multiple generations of the Framework 13, and the Framework 16 shipping by
+the end of 2023.
+
+## How to update
+
+By preference, there will already be a specialised module for your model's configuration.
+
+If not and you have a 13-inch model, the common module under `framework/13-inch/common/default.nix`
+can be imported directly, and the options provided can be used in your own system's configuration.
+
+Alternatively, you can create a new specialisation for your model under `framework` configured for
+that model.
+
+## Changes
+
+### 13-inch profile
+
+All of the existing modules have been reconfigured to be under the `framework/13-inch` folder.
+
+The 12th and 13th gen Intel Framework 13's had their own specialisation modules separately available
+already. To mirror those modules, the 11th gen Intel Framework 13 configuration has been moved to
+`framework/13-inch/11th-gen-intel/default.nix`.
+
+### "Common" modules
+
+Tools / services that are shared among several models are now extracted to their own module under
+`13-inch/common/` and imported by `13-inch/common/default.nix`. There were several tweaks for
+11th gen/12th gen that were duplicated and are now a part of common modules.
