Create an attribution style guide for API users

[JoannaHill]

Background
The Planning Alerts API Contract defines how customers are to attribute Planning Alerts. Currently Attribution is not consistent. Providing a style guide may lessen any account management friction, and ease reliance on client design capability through creating and providing assets

Style Guide with reusable assets to provide to customers when then sign up

• Provide Logo and any other artifacts for designers to utilise
• Propose what text is used and where it could be placed
• Decide what attribution links to (Planning Alerts, Planning Alerts API)

Problem we're trying to solve
Increase attribution
