map (noun) - a diagrammatic representation of an area of land or sea showing physical features, cities, roads, etc.
Maps help people to get from point A to point B and understand the lay of the land. Communities today exist in virtual spaces but they are in many ways mini-societies that have a structure and way of functioning. Just like how maps help guide people to their destinations, communities can help their members by having a 'Getting started' guide or a 'Community Map' to guide members to get the best out of the community.
Here are a few things you could include in the Community Map to make it easier for your members:
Notion - create a 'Getting Started' page to capture all details and maintain it as a guide members can go back to.
Loom - use Loom to create short walkthrough videos of your community.
