fsm_draw_state_diagram command

Hello,

I am not really clear on the 'fsm_draw_state_diagram' command and how to generate a state diagram after implementing your State Machine code. I am trying to generate a state machine diagram for the code below using your implementation. The comment below from one of the documentations wasn't really clear to me and it reads thus:
...................................................................................................................................................................................................................................................................
"State Machine workflows can be visualized using a state diagram.
finite-state-machine generates diagrams using Mermaid Markdown syntax, which can be viewed using the Mermaid Live Editor.
Use the fsm_draw_state_diagram command and point to State Machine workflow class that inheritences from StateMachine.

# class parameter is required
$ fsm_draw_state_diagram --class examples.turnstile:Turnstile

# initial_state parameter is optional
$ fsm_draw_state_diagram --class examples.turnstile:Turnstile --initial_state close
.................................................................................................................................................................................................................................................................

How do I go about this? I already have my code written up. Just need to finish up with the visualization of the state diagram. Will appreciate any help.
