HELP: How to create a page that displays a certain category

So I know it must be possible but I am having a super hard time getting it to work. I just need a page that displays only posts from a certain category. I have downloaded about 8 different plugins for wordpress but none of them have worked right. Thanks

 

Avoid using plugins as it can slow down your blog, especially if this can be done by editing your files. insert wp_list_categories which include one category ID that you want to display in header.php.

 

I may be mis interpreting what you are asking for here but couldn't you just navigate to http://www.yourblog.com/category/categoryname ???

 

You can create a page template and display just the posts from a category.
