help with namecheap website

I don't know much about Namecheap's hosting plan, but I use them for all my domains.

Either way, they use cPanel...which will have one-click WordPress installs.

You shouldn't need too much help with that as it's pretty intuitive...if not, Google's a thing.

If you have cpanel, just check if softacolous or fantastico installed in your cpanel?. If yes, you can use one of them to install wordpress in one clicks. If you don't know how to do it, try to find on google "how to install wordpress using softacolous/fantastico".

In another case, you don't have softacolous or fantastico installed in your cpanel. You can install it manually.
First, create database and username in your cpanel. you should know how to do it, right? if not, try googling how to do it.

After that install wordpress.zip file in wordpress.org. Extract it, and edit wp-config-sample.php. Change all the database name in wp-config-sample.php, then rename it with wp-config.php.

Then upload all of your wordpress files to your ftp account/publichtml.

After all upload processes finished, come to yourdomainname/wp-admin, fill your username and password for your wordpress login. Then login to yourdomainname/wp-admin with your username and password. And voila, your wordpress has been installed.

Note: if you still not clear with my step by step wordpress installation, searching through google, "how to install wordpress manually".
