How do i change the work website?

Please Help me ... my boss has asked me to update the stockist page on the company web site and i have no idea how to do this. if anyone knows how please let me know what i need to do.How do i change the work website?
There are so many ways that is may need to be done, i think its best if you just ask your boss something like ';Do you know how they have edited it in the past?';



If he says no then post a link of the site on here, then perhaps we can try and work it out together. :)



AFTER SEEING WEBSITE:



Ok so your website is using a CMS system call magneto Commerce. I've never used it but you can access the admin panel by going here.

If the system is any good you should be able to follow your nose once you have the username and password. If you get stuck after this i would suggest emailing these guys.
