+If you use fish, the correct lines for your `config.fish` would look like this (consider putting them into the `is-interactive` block depending on your use case):
+```fish
+set -x GPG_TTY (tty)
+set -x SSH_AUTH_SOCK (gpgconf --list-dirs agent-ssh-socket)
+gpgconf --launch gpg-agent
+```
+
 Note that if you use `ForwardAgent` for ssh-agent forwarding, `SSH_AUTH_SOCK` only needs to be set on the *local* laptop (workstation), where the YubiKey is plugged in.  On the *remote* server that we SSH into, `ssh` will automatically set `SSH_AUTH_SOCK` to something like `/tmp/ssh-mXzCzYT2Np/agent.7541` when we connect.  We therefore do **NOT** manually set `SSH_AUTH_SOCK` on the server - doing so would break [SSH Agent Forwarding](#remote-machines-ssh-agent-forwarding).
 
 If you use `S.gpg-agent.ssh` (see [SSH Agent Forwarding](#remote-machines-ssh-agent-forwarding) for more info), `SSH_AUTH_SOCK` should also be set on the *remote*. However, `GPG_TTY` should not be set on the *remote*, explanation specified in that section.
