Question: Im using atom.io for some time now and really like it. there is just one thing im missing. I used to use brackets and sublime before and they both had a feature where you could create the basic structure of a html documents by just typing html.

this would just set the html, head and body tag. created the charset meta, title and link to css file.

I create a lot of html files a day so it would be really helpfull if I know the shortcode or the package which supports this!

Answer: 
You're looking for [`autocomplete-snippets`](https://atom.io/packages/autocomplete-snippets).

Simply type `html` and press `Enter`

Here's a terrible GIF to prove it:

There is a nice Plugin, called emmet: <https://atom.io/packages/emmet>

When you got that, you just have to type `! -> tab` in an empty document. You get pretty much the same result as @hatchet GIF.
