Improve advanced usage guides

[oli-rose28]

What

We completed a content review of all of the existing tutorials and guides in the service. There were consistent issues across the service that we can iterate and improve. This ticket is to track those improvements, rather than having lots of tickets on the backlog.

We will create individual tickets as we are working on the pages to track the actual changes.

Why

It makes sense to make our guidance clearer and easier to use for everyone.

Who needs to work on this

Content Designer

Done when

Each guide:

• explains what technical terms mean
• is clear and easy to understand (this applies more to older guides)
• helps new users to learn advanced topics (some guides feel too concise)
• provides opportunities to learn more about an unfamiliar topic
• links users to the right place (for example, manage your prototype)
• gives examples of where and why you might use something (make these specific to prototyping government services)

Pages

Advanced usage

• Create routes (server side programming)
• Override the service name on one page
• Store data in session
• Use GOV.UK Notify to prototype emails and text messages
• Template partial areas
• Migrate an existing prototype to version 13
