A feature page should describe *one* feature, and reference to other aspects rather then mixing them. This way each individual features can easily be referenced form other pages.

The structure should follow this layout:

1. A H1 headline (the biggest) with the title of the page
2. A short summary of the feature (can include an image but not to large please). This summary is displayed in the summary page of the group of this page.
3. A H2 headline (this can even be an empty headline ('' ====== ====== '') it just clears out that the summary is over
4. All additional content. Ideally with links to tutorials using this feature :)
