<ol>
           <li>Create a parameter backup using Parachute or Mission Planner.</li>
           <li>Paste your configuration in the textbox below. Your OSD items will be displayed.</li>

           <li>Add OSD elements from the list on the right or re-arrange them as you like.</li>
           <li>Copy the generated parachute command to the CLI or the Mission Planner config to a textfile and restore.</li>
