Search Engine Friendly URL or SEF

The first time I created website using joomla, I had this garble url.

Now I would like to make it search engine friendly like this:

Steps:

1.Using ftp locate on your root folder for the file htaccess.txt

2. Right click on the file, choose rename and type .htaccess

3. Login to your administrator panel. 

4. Click Site

5. Then Global Configuration

6. On SEO Settings, click Yes on Search Engine Friendly URLs, Use Apache Mode rewrite and Add Suffix to URLs

That's it! Refresh your new site.
