Before running a deployment, it can be useful to preview the changes that will be deployed, so that you can check to see if any files will be uploaded or deleted.
You can also preview a deployment easily when using the DeployHQ mobile app; just head to any project and tap the Start a new deployment button, then once you're finished configuring the deployment, tap Preview.
A preview will be generated, and a list of file changes will be shown. Additionally, where appropriate any configured build commands or config files will be displayed below your list of file changes.
