Write here your challenge in a very synthetic way
In one paragraph explain why it is important to develop this project
How are you planning to tackle the challenge? Explain a little bit how are you imagining to solve the problem. Diagram can help and even some techniques from Miro board.
Expand your how with the details (use h3 to divide in parts, so your audience know what you are talking about)
Write the details in small paragraphs
Who is your persona? What kind of people will be impacted by your project.
Call for action!!!
Write what you need from your audience. A survey, a comment, a beta test... and explain to them how to deliver to you.
Want to put some links to external references, your personalized website, to your miro... here is the place. (good to put a line divider before)
