Before you can begin a documentation project, you will need to address quite a few questions, including those listed below. FOSdoc can help you resolve these questions so that you can concentrate on the contents.
Have you selected the authors yet, and are you seeking technically experienced editors?
Is it worth employing a (well-known) publisher who can co-ordinate the team of authors?
Do your chosen tools allow the workload to be shared (i.e. do they allow history and versioning, among other things), and are they suitable for different output formats?
Have copyright and exploitation rights for the documentation been clearly and contractually agreed?
How will the documentation be updated and re-released once it is published?
