Just a quick thought I saw when reading the sub-generators part in readme:
Is there a reason why you write:

navigate to http://127.0.0.1:9000/#/ in your browser.
because in other cases you write

navigate to http://localhost:9000 yourself
would be good if this is written the same if it makes no difference
