• multimedia/text content for the first version of an app

• temporary office 365 license if needed, with access to the document repository (we will be using my sharepoint)

• access to the development versions Azure when needed

• I will be ready to discuss with you any details, at the beginning and of course during the development process, I'm open to adopt your way of working.

Then we will fix the project details, in particular: the development and testing approach. You will have a chance to influence the technology and UI decisions.
