Hi Christina,
We store all meeting notes and documents for teams that we onboard in a Drive folder and then we link it to the project. Everyone can then go directly to the folder (if it's shared with them) and access all relevant files for the team. The files are always current because they aren't uploaded into the system.
You could take it another level and have additional folders that specify the types of documents in each for easier navigation as the list of files can get long.
Hope this helps,
Teale
