You can send over-the-air updates containing critical bug fixes and improvements to your users.
## Get started
> If you've published [previews](/review/share-previews-with-your-team/) or created a [build](/deploy/build-project/) before, you may have already set up updates and can skip this section.
To set up updates, run the following [EAS CLI](/develop/tools/#eas-cli) command:
After the command completes, you'll need to make new builds before continuing to the next section.
## Send an update
To send an update, run the following [EAS CLI](/develop/tools/#eas-cli) command:
This command will create an update and make it available to builds of your app that are configured to receive updates on the `production` channel. This channel is defined in [**eas.json**](/eas/json/#channel).
You can verify the update works by force closing the app and reopening it two times. The update should be applied on the second launch.
## Send updates automatically
You can automatically send updates with [EAS Workflows](/eas/workflows/get-started/). First, you'll need to [configure your project](/eas/workflows/get-started/#configure-your-project), add a file named **.eas/workflows/send-updates.yml** at the root of your project, then add the following workflow configuration:
```yaml .eas/workflows/send-updates.yml
name: Send updates
on:
push:
branches: ['main']
jobs:
send_updates:
name: Send updates
type: update
params:
channel: production
```
The workflow above will send an over-the-air update for the `production` update channel on every commit to your project's `main` branch. You can also run this workflow manually with the following EAS CLI command:
Learn more about common patterns with the [workflows examples guide](/eas/workflows/examples).
