This is a short description of your project, listing its main functionality value proposition. Keep it to one single short paragraph with up to 280 characters.
If the project is a work in progress, make mention of it in a second paragraph. Optionally you can include a link to a project kanban board or product roadmap, or include a short checklist to what needs to be completed. Ideally you will keep track of those items the issues tab.
Reflect on the problem you are trying to solve and how you found out about it. Mention interviews with users or public sources that can be used as an evidence that this is a relevant problem. If this is only a personal problem, that's fine; the idea is that the existence of this project can be justified by an existing problem that you, or someone you know, are experiencing.
