+# Upgrade to 1.0.1 from 1.0.0
+1. **Switch IHP version**
+
+    - **IHP Basic**
+
+        Open `default.nix` and change the git commit in line 4 to the following:
+
+        ```diff
+        -ref = "refs/tags/v1.0.0";
+        +ref = "refs/tags/v1.0.1";
+        ```
+
+    - **IHP Pro & IHP Business**
+
+        Visit https://ihp.digitallyinduced.com/Builds and copy the latest v1.0.1 URL into your `default.nix`.
+
+2. **Remake Env**
+
+    Run the following commands:
+
+    ```bash
+    nix-shell --run 'make -B .envrc'
+    nix-shell --run 'make -B build/ihp-lib'
+    ```
+
+    Now you can start your project as usual with `./start`.
