+# How do I start with Node.js after I installed it?
+
+Once you have installed Node, let's try building our first web server\
+Create a file named "app.js", and paste the following code:
+
+```javascript
+const http = require('http');
+
+const hostname = '127.0.0.1';
+const port = 3000;
+
+const server = http.createServer((req, res) => {
+  res.statusCode = 200;
+  res.setHeader('Content-Type', 'text/plain');
+  res.end('Hello World\n');
+});
+
+server.listen(port, hostname, () => {
+  console.log(`Server running at http://${hostname}:${port}/`);
+});
+```
+
+After that, run your web server using ``` node app.js ```, visit http://localhost:3000, and you will see a message 'Hello World'
