How can I include a page in another page and edit it like a section?
All sections are optional, you can remove those that do not apply to your recipe, and add new ones.
Markup to include pages like they are sections, with click to edit.
The markup essentially houses an included page inside of a div. An edit link is present if the user has edit authority.
Change log / Release notes
If the recipe has multiple releases, then release notes can be placed here. Note that it's often easier for people to work with "release dates" instead of "version numbers".
