I need to add an articles tab and page to my website. I want the ability to upload and delete as many articles as I choose. When someone lands on the articles page, I want the site visitor to the see the first 4-5 lines of the article and then have the ability to click on the article from there and after clicking on the article be brought to a separate page where they can read the whole article.
