# Configuring a state machine

{% hint style="warning" %}
This section is deprecated. However, as of now, the Sylius E-Commerce project is still resorting to this configuration so you might want to check it out.
{% endhint %}

You can either use [Symfony workflow](https://symfony.com/doc/current/components/workflow.html) or [Winzou state machine](https://github.com/winzou/StateMachineBundle). The recommended way is to use the `Symfony workflow component`.

If only Symfony workflow is on your requirements you have nothing to do.

But you can configure it explicitly:

## Configuring Symfony workflow as state machine\`

```yaml
sylius_resource:
    settings:
        state_machine_component: symfony
```

## Configuring Winzou as state machine\`

If Winzou state machine is on your requirements you have nothing to do even if Symfony workflow is on your requirements too.

But you can configure it explicitly:

```yaml
sylius_resource:
    settings:
        state_machine_component: winzou
```

## Applying a transition\`

You can create a route to apply any transition

```yaml
app_pull_request_apply_transition:
    path: /pull-requests/{id}/{transition}
    methods: [PUT]
    defaults:
        _controller: app.controller.pull_request:applyStateMachineTransitionAction
        _sylius:
            state_machine:
                #graph: pull_request # name of the graph for Winzou or workflow name for Symfony (optional)
                transition: $transition
```
