**Additional context**
I was trying to follow the instructions here but it didn't work. I setup create and ran a new tunnel on one host, which should be steps 1 and 2 in that section. Step 3 says to simply run `cloudflared tunnel run existingname` on a second host but this doesn't work because it does not have credentials. Since the credentials are created/downloaded when creating a new tunnel with `cloudflared tunnel create xyz`, this step is missing. It is also not clear from the help for the `tunnel` option how you could download credentials for an existing tunnel.

In the end, I copied the credentials files manually from the host that was already working and this seems to have made it work.

It does make me wonder whether these docs are used by staff when demoing since presumably then these omissions would be spotted more easily?
