Architecture diagrams

[ceddlyburge]

It would be good to add some high level architecture diagrams, to aid development. Probably using mermaid.

To include

• Concept (Editing google sheets is easy and familiar for most people, so entering fixtures and results is easy, and from this you can get a fully fledged league table type website for teams and players)
• Types of users (Owner / Administrator, League Editor, League Viewer)
• Inputs (environment variables and google sheet)
• High level code flow
• Maybe high level code structures (although the Model basically describes most of these, so might not be required)

From simon brown's 4s model:

system context diagram

• scope?
• who is using it
• what are they doing
• how do they do it

container diagram

• high level tech blocks
• what are their responsibilities
• how do they communicate
