Prefect Community

Hey in the prefect 2.0 docs it says

```All tasks must be called from within a flow. Tasks may not call other tasks directly.
```
Does this mean we can't call task.run() like in 1.0?

That was quite useful...

Further to this, I'm reading the tutorial getting started docs here

<https://docs.prefect.io/tutorials/execution/|https://docs.prefect.io/tutorials/execution/>

And on this page a task is called with a `.submit` out of nowhere and with no explanation as to what its doing and why.

Maybe worth adding some explanation?

Well there is mention lower down...

```Call .submit on the task instead of calling the task directly. This submits the task to the task runner rather than running the task in-process. ```

You may lose some if you don't mention it earlier in the document though.

There’s also `task.fn()`  which calls the underlying function (which I think is equivalent to task.run() if I’m not mistaken)

<@U024LD633LK> You’re right. Thanks for the feedback. We will add more description on `.submit`
