+## Switch IHP version
+
+Open `default.nix` and change the git commit in line 4 to the following:
+
+```diff
+-ref = "refs/tags/v0.8.0";
++ref = "refs/tags/v0.9.0";
+```
+
+After that run the following command to update your project:
+
+```bash
+make clean
+nix-shell -j auto --cores 0 --run 'make -B .envrc'
+make -B build/ihp-lib
+```
+
+Now you can start your project as usual with `./start`.
+
+
+## Upgrade AutoRoute
+
+If you got an type error related to AutoRoute's `parseArgument` function, you need to also follow this step.
+
+The `parseArgument` interface has been removed as this works out of the box now. To upgrade remove your definitions of `parseArgument`.
