All the posts you write and tag according to certain category will be automatically added to that page.
1. Install PAGES LINKS TO PLUGIN and activate it.
2. Create the page and its url should be like this http://domain.com/category/category name/
EXAMPLE : http://djdarzee.com/category/my-music/
3. If the url of the page is like this,it will automatically connect to the category and show all the posts chronologically.
4. All your posts will appear in the HOME PAGE and that category page.
5. I know you can use this anywhere else by just finding a way for the pages url connecting to the category.
