It is used when the partitions need to be copied before flashing.

+steps:
+  unlock_bootloader:
+    - type: confirm_button
+      content: >
+        As a first step, you need to unlock the bootloader of your device. A bootloader is the piece of software, that tells your phone
+        how to start and run an operating system (like Android). On the device, dial *#06# to launch the service menu.
+    - type: confirm_button
+      content: Go to service info > configuration and check rooting status - you can only continue if it says 'Bootloader unlock allowed":" Yes.'
+    - type: confirm_button
+      content: >
+        Now go to Settings 'About the phone' and then Status. Write down the IMEI of your device. You will need it in the next step.
+    - type: link_button_with_confirm
+      content: >
+        Click on the button to open the instructions on Motorola's official unlocking website to generate an unlock code for your bootloader.
+        Once you got the code write it down somewhere and continue to input the code. 
+      link: https://motorola-global-portal.custhelp.com/app/standalone/bootloader/unlock-your-device-a
+    - type: confirm_button
+      content: Connect the device to your PC via USB. And confirm to continue.
+    - type: call_button
+      content: Press the button to reboot into the bootloader now. When the notification light turns blue, confirm to continue.
+      command: adb_reboot_bootloader
+    - type: call_button_with_input
+      content: >
+        Use your code to unlock the bootloader of your device. Type in the full 18 character code starting with 0x (Example: 0x3EC4F7AD6E0B32B6).
+        If you already did that, you can skip this step.
+      command: fastboot_unlock_with_code
+    - type: call_button
+      content: >
+        Press the button to reboot. Since the device resets completely, you will need to re-enable USB debugging to continue. 
+        Connect your device to your PC via USB. Then confirm here to continue.
+      command: fastboot_reboot
+  flash_recovery:
+    - type: call_button
+      content: >
+        Now you need to flash a custom recovery system on the phone. A recovery is a small subsystem on your phone, that manages updating,
+        adapting and repairing of the operating system.
+        Make sure your device is turned on. You need to reboot into the bootloader again by pressing 'Confirm and run' here. Then continue.
+      command: adb_reboot_bootloader
+    - type: call_button
+      content: Flash a custom recovery (temporarily) by pressing 'Confirm and run'. Once it's done continue.
+      command: fastboot_flash_recovery
+  install_os:
+    - type: call_button 
+      content: >
+        In the next steps, you finally flash the selected OS image.
+        Wait until the TWRP screen appears. Then run the command.
+        This step will format your phone and wipe all the data. It will also remove encryption and delete all files stored 
+        in the internal storage. Then the OS image will be installed. Confirm to run. This might take a while. At the end your phone will boot into the new OS.
+      command: adb_twrp_wipe_and_install
