Start building the NFA by right-clicking on the canvas to create a node. Then, right-click on the new node to create a transition, edit its properties, or delete it. You can pan the canvas by clicking and dragging the mouse. You can zoom the canvas by hovering the mouse over the canvas and scrolling up or down. Additionally, you can import a saved NFA or use one from a list of presets.

When creating a transition between nodes, you will be prompted to press a key on your keyboard to represent the transition symbol. You can use any key, including uppercase values. However, to create an epsilon (ε) transition, you must press the key on your keyboard.

After building the NFA, you can then start converting it to a DFA. This can be done in steps , animated , or all at once . You can revisit previous actions by going backwards . You may drag nodes around to reorganize the visual layout. However, node-editing features are disabled. To change the DFA, you must first change the NFA.
