+This is a sample basic Node.js website using plain HTML files and the built in http and fs modules.
+
+This tutorial will walk you through the creation of a very basic website using only Node.js built in modules. Follow these steps to create a Node.js website:
+
+## Steps
+
+1. Create a folder for your Node.js project.
+2. Create a home page HTML and call it index.html. Add the required HTML tags and some basic content in the index.html file. 
+3. Create a second file and for now, call it another-page.html. Add the required HTML tags and some basic content in the another-page.html file.
+4. Add a link in the index.html page to antoher-page.html. And add a link in the another-page.html to index.html. This will allow for easy testing of pages.
+5. Create a new file called app.js. 
+6. In app.js import the required modules:
+
+```
+var http = require('http');
+var url = require('url');
+var fs = require('fs');
+```
+
+7. Create an http server:
+
+```
+http.createServer(function (req, res) {
+}).listen(8080);
+```
+
+This will start a web server. The server is available to test by opening a browser and using the URL http://localhost:8080/index.html.
+
+8. Inside the `createServer` function add code to fetch the current URL:
+
+```
+var q = url.parse(req.url, true);
+var filename = "." + q.pathname;
+```
+ 
+9. Inside the `createServer` function, after the the previous lines of code, add code to load the appropriate HTML file based on the URL. For example the URL `http://localhost:8080/index.html` will should the index.html file.
+
+```
+fs.readFile(filename, function(err, data) {
+ res.writeHead(200, {'Content-Type': 'text/html'});
+ res.write(data);
+ return res.end();
+});
+```
+
+10. Inside the `readFile` function, add code that will display an error message in case the requested URL does not match an exsting file:
+
+``` 
+if (err) {
+ res.writeHead(404, {'Content-Type': 'text/html'});
+ return res.end("404 Not Found");
+} 
+```
+
+11. To test your Node.js website, open up a terminal, use `cd` to navigate to your project folder, and use `node app.js` to start your file. Then open a browser and visit the URL http://localhost:8080/index.html..
