  def caveats
    <<~EOS
      Install goblin-skiff on both endpoints, then run:
        goblin-skiff user@server
      For UDP jump relays, install this release on each jump host too:
        goblin-skiff -J user@jump user@server
      Open the file/control menu with Ctrl-^ (usually Ctrl-Shift-6), then 0.
      This package does not replace stock mosh or a manual /usr/local install.
      Existing sessions keep running; open a new session after an upgrade.
      --fips-crypto requires a configured FIPS provider; this is not a FIPS
      certification. Source, licenses and setup: https://brew.goblinreactor.com/
