Notes:
Documentation re other data sources brought up to date:
Documentation re other data sources brought up to date - seems to be all up to date as the only data sources we use are CAMs and OpenAq, and we have docs for both.

Decision log brought to date:
Wasn't sure what to add to the decision record, so I left it.

If any areas of complexity in the code are not covered by the above then specific pages written:
Had a chat with Seb, and we think it's a good idea for him to write some documentation for his Global map.
