 If you are the owner of a transmitter that supports the er9X/erSky9X or OpenTX firmwares (Frsky Taranis, Horus or the FlySky TH9X or the Turnigy 9X family) you have the additional option to use a serial protocol to communicate between your Tx and the MULTI-Module. (Owners of Walkera Devo transmitters should look at the [Deviation Tx](http://www.deviationtx.com) project for how to achieve the same end goal). This serial protocol does not require any hardware modifications, but will likely require updating the firmware on your radio. For those willing to do this, there are some nice advantages:
   - The model protocol selection, associated parameters, failsafe and binding is done from the Model Settings menu on the Tx
-  - For telemetry capable transmitters, the telemetry integration is done seamlessly with the Tx firmware. (Note that FrSky TH9X/Turnigy 9X/R transmitters require a telemetry mod to be done before telemetry can work).  Click on the link corressponding to your Tx on the [Transmitters](docs/Transmitters.md) page for more details.

 # How to get started?
 1. Browse the [Protocols](Protocols_Details.md) page to see which protocols you would like on your module
 1. Go to the [Hardware Options](docs/Hardware.md) page to decide which of the MULTI-Module hardware options appeals to you and which RF modules you plan to integrate
 1. Once you have your module, you should review what jumper settings or modifications are required to the module to support serial communication and possibly telemetry
 1. Go to [Compiling and Programming](docs/Compiling.md) page to download, compile and program your MULTI-Module
-1. Finally, you should visit the setup page for your transmitter by clicking on the link corressponding to your Tx on the [Transmitters](docs/Transmitters.md) page to configure the last few settings before you can fly to your heart’s content!!!!!

 # Troubleshooting
 Visit the [Troubleshooting](docs/Troubleshooting.md) page.  Please bear in mind that the MULTI-Module is a complex system of hardware and software and it may take some patience to get it up and running.  Also remember that the developers of the system are actual users of the system.  This means that at any moment in time the system is working perfectly for them.  A corollary to this is that if you are struggling there are likely two scenarios.  First, that the problem is with your hardware or with your configuration, second, and much more unlikely but not impossible scenario, is that you are struggling with a new undiscovered bug.  (The author of this documentation speaks from experience ;-)   Please check the RC Groups forum and search for keywords relating to your problem before posting a reply.  When you do post a reply please so humbly and respectfully – you will find many helpful people there.  In your reply please include as much relevant information as possible and attach compilation output and ```_Config.h``` files as text attachments to keep the forum clean.
