+steps:

+    - type: call_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). You need to boot into fastboot mode by pressing the 'Confirm and run' button. Then continue.
+      command: adb_reboot_bootloader
+    - type: call_button
+      content: >
+        Now you need to get your device ID to get an unlock code from Motorola. Press 'Confirm and run' to get the ID. (You need to toggle 'Advanced Output' here to see it.)
+        Copy it to a separate file to use it in the next step.
+      command: fastboot_get_unlock_data
+    - 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.
+        Copy the code from the last step to the website and follow the instructions there. Then continue here.
+      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_with_input
+      content: >
+        Use your code to unlock the bootloader of your device. Type in the full 21 character code you received by email (Example: 5RTSQCYL7ZJKL4NN35MY). Then confirm an run. Afterwards you can continue.
+      command: fastboot_unlock_with_code
+    - type: call_button_with_input
+      content: >
+        You need to perform the last command again, so reenter the code and run again. Afterwards you can continue.
+      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
+  boot_recovery:
+    - type: call_button
+      content: >
+        Now you need to boot 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

+        Boot a custom recovery (temporarily) by pressing 'Confirm and run'. Once it's done continue.
