Leo has asked me to do a tutorial on installing Wordpress for those who have not used it before.  As I use Justhost I can only go by their install procedure which is very easy, I would imagine most cPanels are similar

1.  This is the JH cPanel  - think of it as a library of "things" , you select an item to open it and see what is inside


2.The simple scripts page opens - you may be able to use this with other sites without having Justhost, I do not know


3.  Tell it  you want to install -


4.  Tell it where you want to install (if you have subdomains you can choose)

Q. Why do I install in the root rather than a file called Wordpress or something ?
A.  So that the url reads www.mysite.com and not www.mysite.com/wordpress

Hope this helps someone and gives them the confidence to get going.  I think all the other information you need is in Leo's tutorial videos
