Stuck at the first project

Anyone can help me, i got stucked at my first project

So you added a bunch of things. You need to only do exactly what you are told to do:

Add a DOCTYPE tag for HTML5 to the top of the blank HTML document in the code editor. Under it, add opening and closing html tags, which wrap around an h1 element. The heading can include any text.

You’ll have projects later where you can get creative.
