-== Installation
-
-       EasyMotor needs to be rigidly attached in the airframe, and the
-       long axis of the circuit board needs to be aligned with the axis
-       of flight.  By default, the round beeper on the board should be
-       "up" towards the nose cone, and the screw terminal strips should
-       be "down" towards the fins and motor nozzle end of the rocket.
-
-       === Power Switch and Battery
-
-               In addition to the circuit board itself, EasyMotor needs 
-               a power switch and battery to operate.  Unlike most other 
-               Altus Metrum products, EasyMotor does not work with 
-               single-cell LiPo batteries.  That's because commonly
-               available inexpensive pressure sensors need 5V, which is
-               more than a single-cell LiPo provides.  Any battery that
-               provides from 6.5 to about 15 volts should work.  Good 
-               choices are the common 9V alkaline battery, or the very 
-               small and light A23 12V alkaline batteries.
-
-               Because he often mounts EasyMotor to the motor's forward 
-               bulkhead instead of to the airframe itself, Bdale often 
-               uses a length of "shooter wire" from an e-match or used 
-               motor igniter as a power switch, routing the wire out of 
-               the typical fin can vent hole and using "twist and tape" 
-               to power up the board.  Whatever works!
-
-       === Pressure Sensor
-
-               The primary motivation for designing EasyMotor was to have
-               a reliable way of recording motor chamber pressure during
-               flight.  To that end, EasyMotor supports attachment of a
-               low-cost analog pressure sensor.  The board provides 5V
-               to power the sensor, and an input for measuring and 
-               logging the output voltage from the sensor.
-
-               The kind of sensor EasyMotor is designed to work with
-               takes 5V in and has a linear analog output that ranges
-               from 0.5V at 0 to 4.5V at the maximum pressure supported
-               by the sensor.  Very inexpensive sensors that have a 
-               "1/8 NPT" threaded input, a "Buick-style" 3-pin connector,
-               and typically ship with a short cable and mating 
-               connector, are readily available on eBay and AliExpress.
-
-               To log in-flight chamber pressure, a typical approach
-               might be to drill a 1/8" sampling hole all the way 
-               through the center of the motor's forward closure, then
-               drill and tap partially through the closure with a "1/8
-               NPT" pipe tap.  Fill the touch hole with grease, screw in 
-               the pressure sensor, and attach the sensor leads to 
-               EasyMotor.
