Firstly, it is not recommended to create a dynamic (database driven) category list on the index page as this could cause database loading problems if your home page is requested too frequently.

search.php?q=category:Category Name:
...so the HTML you need to add would be (for example):

(remember to use the + sign in the URL in place of a space)
Hope this helps!
