How can I edit a specific item on my website's front page on Magento

I would like to get some help with finding a particular item that shows in my website's homepage. I'm trying to edit the page source code by using Bluehost online File Manager. The开发者_JAVA百科 thing is I couldn't find the specific page where I can find the relevant code to edit. I bought this website source code from a company that installed it on the servers and now I want to edit inside stuff by myself.

There is no single file responsible so put the file manager away. Mostly the front page content is controlled from the administration in the menu CMS > Pages. Look for "Homepage" in the list that shows and click it to edit.

Go to admin side: Catalog->manage products.

Select product then click on it. Then you are able update the info related to this product.
