### YAML File Format

```yaml
version: "1"

global:
  mountpoint: "/home/user/mnt/{{name}}"

filesystems:
  - type: "gocryptfs"
    name: "Work - SSH Keys"
    encrypted_path: "/home/user/.ssh/keyring.work"

  - type: "sshfs"
    name: "Personal - Media Server"
    remote_user: "user"
    remote_host: "mediaserver.local"
    remote_path: "/mnt/largedisk/music"
    remote_port: 22

  - type: httpdirfs
