+# 1. Create new temporary instrument
+In Air Manager, navigate to the `create/edit` tab.
+
+1. Click `New+` to create a new instument. Details don't matter as we delete this again later.
+2. Select the new Instrument in the list.
+3. Click "Folder" in the menu and find the folder `OPEN_DIRECTORY`. <br>
+This is where insturments are installed. <br>
+Pin it to the favorites in Explorer for easy access.
+4. You can delete the test instrument.
+
+# 2. Install the GNS430 Instrument
+1. Download this repository
+2. move the gns430-hardware folder into `OPEN_DIRECTORY``
+3. The Instrument is now installed.
+
+# 3. Use the Instrument in a Panel
+1. In AirManager, go to the `home` tab.
+2. Select the panel in the list on the left.
+3. Click `Instument+`in the Ribbon Menu.
+4. Find `GNS430 Hardware` and add it.
+5. Open the instrument list by click the triangle next to the panel in the list.
+6. Select `Generic - GNS430 Hardware`
+7. Scroll down to user properties and select the pins to which the cables were soldered.
+8. Have fun.
+
+# Hints
+## Arduino Channels
+Arduinos have assigned channels. This channel is selected whe flashing the arduino (Flash Menu).
+In Step #3, Channel 0 Corresponds to Channel A, 1 to B, 2 to C, and so forth.
+
+## Available Pins
+Do not use Pins D0 and D1, as they are used for serial communication between airmanager and the arduino.
+You can use Pins D2 and upwards.
+
+## Default assignment
+The Buttons and Encoders have a default assignment, which is loaded when adding the instrument.
+Changes to the selection are stored until the instrument is removed from the panel.
+It will reset to the default when the instrument is added again.
