[tahoe-dev] Remove node?

[Anders Genell]

Hi list!

I'm new here so please excuse my breaking of any code of conduct. 

We are some friends setting up a small Tahoe grid to use as cloud based backup solution. A friend runs the introducer and I run a storage node connected to it. More nodes to come as more friends join in. When testing things I created a node on one machine but then decided to run my node on a raspberry pi as a low power server. I didn't manage to move the previous node to the pi so I created a new. I now would like to remove my old node from the grid but cannot find any instructions about how to accomplish that. 
I'm sure I've overlooked something obvious so I humbly ask for someone to point me in the right direction. 

Best regards,
Anders
