+# Display Installomator Progress with SwiftDialog in Jamf
+
+Installomator 10 has functionality to communicate with [Bart Reardon's swiftDialog](https://github.com/bartreardon/swiftDialog). When you set the `DIALOG_CMD_FILE` variable Installomator will write progress for downloads and installation (with pkgs) to the command file which allows swiftDialog to display the progress.
+
+However, you have to launch and setup swiftDialog to display a window with a progress bar before Installomator launches and also make sure swiftDialog quits after Installomator has run. This may seem complex at first but allows to configure swiftDialog just for your case without needing to modify the Installomator script.
+
+Here are some example script that would run before and after Installomator to display a swiftDialog window and quit the process after. Since Jamf Pro executes scripts in alphanumerical order, the names are chosen accordingly, to ensure proper order.
+
+## Setup in Jamf Pro
+
+To show Installomator progress with swiftDialog from a Jamf Policy, you require three scripts:
+
+- `00_Prepare_SwiftDialog.sh`: Configures and displays the swiftDialog window
+- `Installomator.sh`: (v10 or higher)
+- `zz_Quit_SwiftDialog.sh`: quits swiftDialog
+
+Add these three scripts to your Jamf Pro and create a policy with these three scripts. The names are chosen that the script appear in the correct order. If you rename the scripts in Jamf Pro, this may disrupt the order and the workflow will not work anymore. The "Priority" of the scripts in the policy should all be the same value.
+
+The different scripts require a set of parameters. We will use the `googlechromepkg` label as an example.
+
+`00_Prepare_SwiftDialog.sh`
+
+Parameter 4: `/var/tmp/dialog` (Path to the swiftDialog command file)
+
+Parameter 5: `Installing Google Chrome...` (text shown in the swiftDialog window above the progress bar)
+
+Parameter 6: Path to or URL for an icon in swiftDialog. This can be a path on the client or a URL. See Dan Snelson's advice on how to get icon URLs for Self Service icons: https://rumble.com/v119x6y-harvesting-self-service-icons.html
+
+`Installomator.sh`
+
+Parameter 4: `googlechromepkg` (the label to install)
+
+Parameter 5: `DIALOG_CMD_FILE=\var\log\dialog.log` (the swiftDialog command file, this has to be the same value as parameter 4 in the previous script)
+
+Parameter 6: `NOTIFY=silent` (disable Installomator notifications, optional)
+
+You can add more configurations to the Installomator script when needed.
+
+`zz_Quit_SwiftDialog`
+
+Parameter 4: `/var/log/dialog.log` (the swiftDialog command file, this has to be the same value as parameter 4 in the first script)
+
+Then setup the remainder of the Jamf Policy to your needs. This works best with Self Service policies.
+
+When you run the policy, the first script will configure and display swiftDialog. Installomator.sh will download and install the app while writing the proper update commands to the file set in `DIALOG_CMD_FILE`. The final script will quit swiftDialog.
