+# Node.js
+
+Altis supports running Node.js applications alongside WordPress, utilizing WordPress as a headless API.
+
+## Enabling Node.js in Local Server
+
+Node.js can be enabled in Local Server by adding `extra.altis.modules.local-server.nodejs` in the project's `composer.json`
+
+```json
+{
+   "extra":{
+      "altis":{
+         "modules":{
+            "local-server":{
+               "nodejs":{
+                  "path":"../altis-nodejs-skeleton"
+               }
+            }
+         }
+      }
+   }
+}
+```
+
+`path` is relative to the directory where `composer.json` lives.
+
+## Setting Node.js Version
+Similar to configuring the Altis infrastructure, the Local Server determines the Node.js version to use based on the `engines.node` value found in the `package.json` at the specified `path`.
+
+## Running Development Server
+Once configured, the Local Server executes `npm run dev` inside the Node.js container at the specified path. This command watches for changes and recompiles necessary files.
+
+## Accessing the Application
+This setup makes the application accessible at `https://nodejs-{project-name}.altis.dev`.
