+## Windows Note
+
+### Make command not available
+
+On Windows, the `make` command from the Makefile may not be available by default. You have two options:
+
+**Option 1: Install Make** (recommended for future use)
+
+=== "Using Chocolatey"
+
+    ```powershell
+    choco install make
+    ```
+
+=== "Using winget"
+
+    ```powershell
+    winget install GnuWin32.Make
+    ```
+
+After installation, restart your terminal and `make serve` should work.
+
+**Option 2: Use Docker commands directly**
+
+If you don't want to install Make, you can run the Docker commands directly as shown in the "Without Make (Windows)" tab in the [Starting the local env](#starting-the-local-env) section above.
+
+Both approaches will set up your development environment successfully.
