Things have been very easy, until and unless you don’t know how they work.
Installing the API of wordpress on your domain is like that easy.
How to install WordPress on your domains?
Simply download the latest WordPress API from http://wordpress.org/download/
After successful download, extract it on your specified folder, like your Desktop, or any other root drives.
Goto the folder where you have extracted it, and rename the file: wp-config-sample.php to wp-config.php
Open this same file in your text editor, and change the following variables values to your website’s database settings:
DB_NAME
DB_USER
DB_PASSWORD
This is it.
Now copy all the files along with their folders on your website, and access your website.
Visit your website..
WordPress is now ready on your web to get configured.
P.S. If your website contains the folder wwwroot in it, then put all these files in that folder.
