To get started on your project it is important to know the requirements of the software you are creating. While the proposals for all the projects should have 10 features, you need to put these into user story format as issues on GitHub. You will also need to meet with your customers to get clarification on the requested features. If you haven’t had me for Software Engineering of have just forgotten about user stories, you can refresh yourself with this information.
When you are done creating your user stories, meet with your team and break the stories down into tasks using the task list feature of GitHub issues.
At least 10 issues that represent user stories for the project in the GitHub issues system complete with tasks to complete each issue.
