Add instructions to edit ~/.ssh/config so that it contains an entry for
ssh.balena-devices.com that uses the newly added key, otherwise balena ssh
won't know which key to use.

If you do not have an existing key, you can follow [GitHub's documentation][github-ssh], skipping the step about adding the key to your GitHub account, and instead adding the key to your {{ $names.cloud.lower }} account.

Once you have added a key your your account, you should also add an entry for `ssh.balena-devices.com` to your `~/.ssh/config` file so that the `balena ssh` command knows to use this key:

Let me start with: Thank you for the contribution! 👍

you should also add an entry for ssh.balena-devices.com to your ~/.ssh/config file

Hmm, this is not usually necessary though. I am considering two possibilities:

  1. You meant to have a simple / standard setup with a single key for all hostnames, but balena ssh didn't work for you until you added ssh.balena-devices.com to ~/.ssh/config. In this case, we should debug what went wrong and fix it, so that it works without extra configuration in ~/.ssh/config, and we might then document "watch out for xxx"...

  2. You have a complex setup with separate ssh keys for multiple hostnames, and deliberately chose to use a different key for balena / ssh.balena-devices.com. I understand that ssh key configuration is a step that many users struggle with even in the simple scenario of a single ssh key for all hostnames, so I'd be wary of documenting extra setup steps that would become extra opportunity of misconfiguration and failure. If the intention was to document the steps for this complex setup case, then I would suggest adding a separate section in this document that had a title such as:

## Using a separate ssh key for balena (advanced and optional)

If you need to use a separate ssh key for balena than the ssh key(s) you use for
other services, ...

By the way, in this second scenario, we should keep in mind that balena ssh supports Windows as well, with shells like PowerShell or cmd.exe, and the built-in ssh client provided by Microsoft. Does the ~/.ssh notation even works in cmd.exe? Maybe it does, but it's something that needs confirmation before we document this configuration.

It's the second setup. I have separate ssh keys for separate services, and without the entry in the .ssh/config file it doesn't use the correct key.

The windows version of ssh provided by Microsoft supports the ~/.ssh notation, with ~ being mapped to %USERPROFILE%.

I'll update shortly with a separate section.
