Reorg of the WordPress tutorial (PR #247 ) prompted a request for edits to the first part of the tutorial from @odwdinc.

Edits to the content of the tutorial will be done as a separate PR.

Requested changes:

1. Current content:
Open a text editor and perform the following:
Copy the content listed below into the new file /etc/httpd/conf.d/httpd.conf.
Question:
How do you open the text editor? as this is a procted file and you will need root the dir dus not excit
so you need to creat the dir befor you can add the file.
Suggestion/comment:

sudo mkdir -p /etc/httpd/conf.d
sudo nano /etc/httpd/conf.d/httpd.conf

2. Current content:
To ensure a successful setup, edit the new index.html file. Change the original text from
