Welcome to the 737NG series of aircraft
I hope to release updates at about 6 month intervals.

Getting Started
At present the best(if not only)way to start the aircraft is to use the Autostart
function on the main menu.This will be worked on at up coming releases. 
Be aware that it takes about 30sec for the engines to come up to idle.
Once the engines have been started for the first time they can be shut down
by the cuttoff leavers and restarted again by using the start switches on the
overhead panel and raising the cutoff leavers.
To change liveries just select it from the liveries section of the 737 section
in the main menu
The Pushback can be operated by selecting it in the equipment menu in the main
menu

Activating the pick animations
The animations use the LMB(Left Mouse Button) to turn things on also to increase
a value or turn a knob clockwise.In the case of the parking brake the LMB toggles
the brake on and off
The MMB(Middle Mouse Button) is used to turn things off also to decrease a value
or turn a knob anti clockwise
I am told some people do not have a mouse with a MMB at this stage the only fix
is to get a mouse with a MMB.

Autopilot
The autopilot is operated by CMD A switch on the far right of the autopilot panel
The parts of the autopilot that currently work are.
Altitude hold/aquire
Heading hold
VOR/LOC
Approach
To disconnect the autopilot click the Disconnect bar at the far right of the panel.
Note that the aircraft will not hold the glideslope on approach at speeds above.
170kts.It will fly through it and results will become unpredictable.
The CRS window will select the radial that the aircraft will fly to or away from
a radio becon

Autothrottle
At present the only setting that works is the speed hold function this is activated
by selecting the arm switch to on and selecting the speed button And adjusting the
speed with the speed knob.
To disengage the autothrottle deactivate the arm switch with the MMB.

Efis Panel
The Efis panel is the smaller panel to the side of the autopilot panel.
What works on this
The two VOR/ADF switch's.These need to be switched on to get the radio
instruments to show on the MFD(Multi Function Display) 
The lower left rotary switch selects the mode that is selected on the
MFD also the CTR button selects between a full and partial compass rose.
The lower right rotary switch adjusts the range for the AI traffic on the
MFD also the TRF button turns the AI traffic display on or off.

Radio
The radio's can be adjusted on the centre panel but at present this is
not reliable so it is probably best to adjust freq's from the equipment
menu on the main menu.

Overhead and Centre Panels
At present the only thing that works on the overhead panel is the engine
start switches and on the centre panel only the comm's and nav radio's

Flying the Aircraft
On reaching about 140kts the aircraft should rotate.
There are only two warnings at present that is an overspeed warning at 340kts
and a stall warning at 150kts clean and 120kts full flap.
For landing you will need the speed brake set to armed or the aircraft is
likely to bounce unless you can put it down real gentle also it is a good
idea to set the autobrake to 2 or greater.The switch for this is just above
the EICAS panel.

If you have any questions about flying this aircraft could you direct then
to the 737NG thread on the Flightgear Forum.

Thank You
