const sm = new StateMachineBuilder()
  .withStates([locked, unlocked])
  .withTransitions([

  ])
  .build(locked);
```

You can find the full example in the [examples](./examples/) folder.

# Installation

if you use the [Deno](https://deno.land), just add following to your
`import_map.json`

```json
{
  "imports": {
    "it-fsm": "https://git.pleshevski.ru/pleshevskiy/it-fsm/src/commit/c182728810e9fabcb6bb2b3091bbeabf439bef2d/fsm.ts"
  }
}
```

or you can use branch
`https://git.pleshevski.ru/pleshevskiy/paren/raw/branch/main/`

> **Note**: Use always a specific commit instead of branch

If you use the Node.js or in a browser as ES module, you may need to install it
as follows, and additionally you can add import maps for client side.

`npm install --save it-fsm`
