Collaborator documentation

## User Story

**As a** _collaborator_,

**I want** _to have access to documentation_

**so that** _I can guide my development work, be aware of what the application does or shall do and participate in the long term support of the product_.

## Conditions of Satisfaction
- I know what the goals of the project are
- It is clear to me what the application is expected to do
- It is clear how it is intended to work in various environments
- I can modify the documentation if it is inaccurate
