An algorithm linked to the web that automatically updates whenever new information is added to the internet.

A website that has special features for collaborative editing by its users.

A living document that may hold contributions over time from many different authors or sources.

A run book of exactly how to use and interact with a given product or solution.

An online record of all of the knowledge articles that a customer might need when they contact the help desk.

Each user story has its own wiki page.

The acceptance tests for a given user story appear on a wiki page of that user story.

Features (which can be thought of as sets of user stories) have their own wiki page with a link to each user story connected to the feature.

There can be at most 20 user stories per feature because more than 20 makes it too hard to track them all.

Create a wiki page for each Feature, as features can become complicated and having too many grouped together can be confusing.

Clearly document what the Feature is intended to provide for the user so that there is no doubt of the desired outcome.

Explain any use cases or scenarios that are not covered by the Feature so that there is as much context available as possible.

Use any structure that you want for Features and user stories as long as the users of the wiki can understand the documentation and gain the information they need quickly.
