Sometimes the person who installed and customized GPTree is not the same who adjust and makes prompt engineering. So we need a short tutorial how to

• get access to the prompt
  -- via a direct connected monitor / keyboard
  -- via SPFT (FileZilla) << preferred
  -- via SSH (Putty)

• document the location of the file / path
  -- where to finde /personas.json

• editing personas.json
  -- promt at position:
  "prompt": "Du bist in der Rolle eines lustigen Quittenbaums, ...
  -- some information about JSON
  -- brackets, quotation marks, line breaks
  -- editor / encoding
  -- backup strategy, have ever a working file

• additional audio files in /audio/personas/
  -- directory logic
  -- how to create them

• error handling
