+### Update your scripts
+
+You will also need to update your scripts within your `package.json` to reflect the fact that Nuxt will now produce a Nitro server as build output.
+
+#### Static target
+
+If you have set `target: 'static'` in your `nuxt.config` then you need to ensure that you update your build script to be `nuxt generate`.
+
+```json
+{
+  "scripts": {
+    "build": "nuxt generate"
+  }
+}
+```
+
+#### Server target
+
+For all other situations, you can use the normal `nuxt build` command.
+
+```json
+{
+  "scripts": {
+    "build": "nuxt build",
+    "start" "node .output/server/index.mjs"
+  }
+}
+```
+
 ### Update `nuxt.config`
 
 Please make sure to avoid any CommonJS syntax such as `module.exports`, `require` or `require.resolve` in your config file. It will soon be deprecated and unsupported.
