+#Documentation ToDos
+1. Documentation on all the FlySky boards: (MikeB?)
+   - SKY board	erSky9x
+   - AR9X board	erSky9x
+   - 9Xtreme board	erSky9x
+   - AR9X UNI board
+1. Add to the troubleshooting page
+1. Document the OrangeRx Transmitter module (Mikeb?)
+1. enabling Serial on the DIY PCB page
+1. lots of pictures mentioned between the {} markers
+2. Add how to wire the antenna switcher in the "solder your own board and use 4-in-1 Rf module (add pictures of the wires from the ATmega pins to PE1 and PE2)
+3. Must this be added to the (Compiling for Taranis)Also, if you are using a Taranis, then you need to invert the telemetry as shown:
+Code:
+//Uncomment to invert the polarity of the telemetry serial signal.
+//For ER9X and ERSKY9X it must be commented. For OpenTX it must be uncommented.
+#define INVERT_TELEMETRY1
+1. ~~restructure the transmitter setup documentation~~ 
+   - ~~PPM setup all on one page~~ 
+   - ~~Serial setup by Transmitter~~ 
+
+1. PPM Telemetry: added different serial speeds based on protocol for none inverted telemetry:
+FrSkyD (Incl Hubsan): 9600bps 8n1
+FrSkyX: 57600bps 8n1
+DSM: 125000bps 8n1
+I've done this if people wants to connect something (arduino, bluetooth,...) behind the module to display telemetry when used in PPM mode. It's using the default speed of the original transmitter.
+This is not something supported by er9x or ersky9x which are meant to be used in serial mode. 
+1. Someone to add the Build the board from scratch if it is still relevant
