An open source project is only successful if it has users. You may be the only user, and not be concerned about attracting other users, however, if you want to grow your community and attract developers then you need to attract additional users. This means you need to market your project to those users. One aspect of this marketing is to maintain a set of marketing focussed documents. These will include (but not be limited to):
- A description of the project
- A feature list and roadmap showing what currently works and what it is hoped will work in the future
- A clear statement about the status of the project
- A description of the types of people the project is intended to appeal to (what fields of expertise, what needs)
- A statement about licencing, copyright and project governance
- Detailed install instructions for installation and experimentation
- A change log that indicates the important changes between released versions of the software
- Project communication tools (Mailing list, issue tracker, version control)
- Screenshots and/or screencast of early mockups or prototypes
