To install this instrument into your aircraft, you need to do the following:

1.	Add flarm.nas to your aircraft's list of included nasal files:
	<nasal>
		...
		<flarm>
			<file>Aircraft/Instruments-3d/glider/flarm/flarm.nas</file>
		</flarm>
		...
	</nasal>
	** Note that it is important to put the file into <flarm></flarm> tags, as the animation xml may in the future reference the instrument by that name
2.	Add the model to your aircraft:
		There are two models available, the standard, full-size FLARM and a smaller FLARM (v3) display for integration into a panel.
		You can use either or both of these:
	<model>
		<path>Aircraft/Instruments-3d/glider/flarm/v3_display/flarm_v3.xml</path>
		...
	</model>
	<model>
		<path>Aircraft/Instruments-3d/glider/flarm/traditional/flarm_traditional.xml</path>
		...
	</model>
3.	If you are using a custom electric system, make sure the FLARM is supplied at /systems/electrical/outputs/flarm when appropriate
4.	Add sound effects for this FLARM, e.g. by using the block below and adjusting it to fit:

<flarm_info>
	<name>flarm new contact</name>
	<mode>once</mode>
	<path>Aircraft/Instruments-3d/glider/flarm/flarm_new_contact.wav</path>
