Learning to describe problems is hard, but it is an important part of learning how to code.
Also, the more you say, the more we can help!
Your code has h1 and h2 elements, which are using for headings. They consist of an opening tag (e.g. <h1>), text content (‘CatPhotoApp’) and a closing tag (</h1>). Directly below the h2 element, you should now create a p (paragraph) element using the same syntax. You should have an opening p tag, the specified text content and a closing p tag. You should not have h3 tags (which are another type of sub-heading element).
