3. Go to the second Pyflap folder (where manage.py is) and run python manage.py runserver to run the app.

It is necessary to setup the frontend with npm too.

1. Install your npm

Instructions to use the Finite Automata page.

The buttons in the green box:

1. Use to move the nodes (hold left click and drag).
   1. This button is used to edit TRANSITIONS too, just double click in any transition with it.
2. Add a new state (node) clicking in any position of the canvas with the left mouse button.
3. Remove state (node) or transition (edge) by clicking in it with left mouse button.
4. Create a transition between 2 states, by draging and drop from one state to another (with left mouse button). To create loops, just drag a little bit off the node.

The buttons in the pink box:

1. Mark node as initial (with left mouse). It will be represented as a triangle (like q0 in the image).
2. Mark/Unmark node as final. To mark use the left click, to unmark use right click. q2 is representing a final node, with the red color.
