GGIRCS documentation curation

[dleard]

Assess the CIIP repo's documentation. Things to consider:

• What is outdated
• What is missing
• Is it organised in a way that makes sense and is discoverable

Todo:

• Remove or update outdated documentation
• Create a list of suggestions for documentation that should be added
• Re-organise documentation if it is not discoverable following our documentation organisation strategy

Documentation organisation strategy:

• A docs directory at the root of a repo
• Separate doc files with names that clearly describe what the doc file contains
• Appropriately named sub-directories where there are several related individual doc files
