This makes it more clear as to how the various builders utilize the Procfile, and also ensures we don't have conflicting information anywhere.

You can also customize the run command using a `Procfile`, much like you would on Heroku or
with a buildpack deployed app. The `Procfile` should contain one or more lines defining [process types and associated commands](https://devcenter.heroku.com/articles/procfile#declaring-process-types). The commands in your app's Procfile will be passed to `docker run` to start your process(es). Here's an example `Procfile`:
```Procfile
web: bin/run-prod.sh
worker: bin/run-worker.sh
```
And `Dockerfile`:
```Dockerfile
FROM ubuntu:20.04
WORKDIR /app
COPY . ./
CMD ["bin/run-dev.sh"]
```
When the above example is deployed, the `web` process is started, with the command `bin/run-prod.sh` executed in the container. All other processes must be scaled up separately. If the app's `Dockerfile` contains an `ENTRYPOINT` directive, the command specified in the `Procfile` will be passed to that entrypoint script as an argument.
See the [scaling apps documentation](/docs/processes/process-management.md#scaling-apps) for more information on how process scaling is performed.
See the [app.json location documentation](/docs/processes/process-management.md#changing-the-procfile-location) for more information on where to place your `Procfile` file.
See the [Procfile documentation](/docs/processes/process-management.md#procfile) for more information on how to specify different processes for your app.
