Documentation for Shutdown

I have read the main documentation and I cannot find any instructions for proper shutdown.

Can someone provide a link to such?

You are correct, we do not explain that well at all. Apologies. We do have a button that will do a shutdown and it is only directly exposed as a button on the ‘sonar board’. You can if you don’t have a sonar board make a button to go from Raspberry Pi GPIO 6 which goes to pin 31 of the large 50 pin connector, P702, to pin 30 that is very near on P702. See this ‘learn’ page for a table in the middle that mentions this shutdown feature:

I do a great deal of improvements to the Learn pages and will get this exposed in a less buried location for sure. Thanks for the inputs. This had been discussed as a possible feature for future MCB boards as well I should note.
