Other developer guides

As part of our vision to make learning easier, we want to produce a number of "developer guides" - on this page: https://digital.nhs.uk/developer/guides-and-documentation/developer-guides.
We already have plans for a GP software developer guide and a PDS developer guide. This feature is to deliver developer guides on other topics, such as social care, secondary care or urgent and emergency care.
We welcome suggestions from developers as to what guides they would like to see in the comments below.
