1. The Workflow component provides tools for managing a workflow or finite state machine.

2. composer require symfony/workflow

3. require the `vendor/autoload.php` file in your code

2. Creating a Workflow

1. The workflow component gives you an object oriented way to define a process or a life cycle that your object goes through.

2. Each step or stage in the process is called a `place`(状态).

3. You do also define `transitions`(变化) that describe the action to get from one place to another.

4. A set of places and transitions creates a definition. A workflow needs a Definition and a way to write the states to the objects

2. A workflow is a model of a process in your application.

3. A state machine is a subset of a workflow and its purpose is to hold a state of your model.
