 Notes:
 - model/type/number of channels indicated on the RX can be different from what the RX is in fact wanting to see. So don't hesitate to test different combinations until you have something working. Using Auto is the best way to find these settings.
 - RX output will match the Spektrum standard TAER independently of the input configuration AETR, RETA...
 - RX output will match the Spektrum standard throw (1500µs +/- 400µs -> 1100..1900µs) for a 100% input. This is true for both Serial and PPM input. For PPM, make sure the end points PPM_MIN_100 and PPM_MAX_100 in _config.h are matching your TX ouput. The maximum ouput is 1000..2000µs based on an input of 125%.
    - If you want to override the above and get maximum throw (old way) uncomment in _config.h the line #define DSM_MAX_THROW . In this mode to achieve standard throw use a channel weight of 84%.
- - TH_KILL is a feature which is enabled on channel 15 by default (can be disabled/changed) in the _config.h file.

-**Notes**:
-* The Vantac MPM Lite module most likely already has the USB Bootloader flashed on it. You can directly use the [upload via USB](#upload-via-usb) method. Early modules' bootloader was however not booting everytime, if this is the case you need to upgarde it.
+Tools are only required if a multi module does not have a USB port, a working bootloader or an integrated FTDI adapter:
+* The latest iRangeX IRX4+ modules most likely already have the USB Bootloader flashed on it. You therefore don't need the FTDI adapter below and don't need to open your module to flash it.
 * The latest jumper modules have an integrated FTDI appearing as a CP2102 device on the computer. You therefore don't need the FTDI adapter below and don't need to open your module to flash it.
+* The Vantac MPM Lite module already has the USB Bootloader flashed on it. You therefore don't need the FTDI adapter below and don't need to open your module to flash it. **Modules' bootloader however might not be booting everytime depending on the radio, if this is the case you need to upgrade it.**

+You are still unsure if your module can be flashed without tools or opening it? Here is how to quickly check:
+* Power off the TX
+* Connect a USB cable to the module, if the module does not have a USB port then you must open the module to flash it using an external FTDI
+* Connect the cable to the PC and power on the the TX
+* If the PC does not complain about a none working device being plugged then you are good to upgrade via USB directly without the need of any tools or opening the module.

+## Option-1 Update Firmware using Precompiled Binaries
+If you don't need/want to customize the multi module firmware then you can use pre-compiled binaries available [here](https://github.com/pascallanger/DIY-Multiprotocol-TX-Module/releases).
+
+**STM32 Builds (file names beginning with 'Multi-STM_')
+ -   All radio modules and protocols are included in all builds
+ -   Files with TXFLASH in the name are built with a bootloader for flashing from a transmitter OR via the module's USB port (eg. Multi-STM_TXFLASH_INV-vX.X.X.XX.bin)
+ -   Files with FTDI in the name are built without a bootloader for flashing using an FTDI adapter (eg. Multi-STM_FTDI_INV-vX.X.X.XX.bin)
+ -   OpenTx/JumperTX version (files with OPENTX in the name) have the MULTI_TELEMETRY parameter enabled (eg. Multi-STM_TXFLASH_INV_OPENTX-vX.X.X.XX.bin or Multi-STM_FTDI_INV_OPENTX-vvX.X.X.XX.bin)
+
+[Flash-Multi](https://github.com/benlye/flash-multi) is the recommended Windows utility for flashing pre-compiled firmware to any STM32-based Multiprotocol TX module. Firmware upload can be performed using the built-in USB connection or via an external FTDI adapter.

+After a succesful flash your Module is now updated to the newer version firmware using the most common options. To change specific configured options you would need to use Option-2, Compile and flash update using Arduino IDE.

+# Option-2 Compiling and Updating Firmware
+
 ## Preparation
+
+Multiprotocol firmware can be compiled and uploaded with your customized firmware using the Arduino IDE. The guide below will walk you through all the steps in many details, don't be afraid by the length it is in fact simple!
+
 ### Install the Arduino IDE
 1. Download and install the Arduino IDE. The currently supported Arduino version is 1.8.5, available for [Windows]( https://www.arduino.cc/download_handler.php?f=/arduino-1.8.5-windows.exe), [Mac OSX](https://www.arduino.cc/download_handler.php?f=/arduino-1.8.5-macosx.zip) and [Linux (64-bit)](https://www.arduino.cc/download_handler.php?f=/arduino-1.8.5-linux64.tar.xz)
 1. It is recommended to upgrade Java to the [latest version](https://www.java.com/en/download/)

 **Note:** The line `Reset via USB Serial Failed! Did you select the right serial port?` or a warning line stating that the device could not be reset is **not a problem**.

-## Flashing pre-compiled binaries
-Pre-compiled binaries are available [here](https://github.com/pascallanger/DIY-Multiprotocol-TX-Module/releases).
- **Multiprotocol_V1.X.X_STM32.bin** files are for transmitters with support for hardware telemetry inversion, such as Turnigy 9X, 9XR, 9X+.
- **Multiprotocol_V1.X.X_STM32_INV.bin** files are for tranismitters which require telemetry inverted in the module firmware, such as Taranis.
-
-If you want to flash a pre-compiled binary file (like the Release .bin files) you will use the same USB-to-TTL adapter as [above](#connect-the-programmer).  
-
-You will also need to download the **ST Flash Loader Demonstrator** from [here](http://www.st.com/content/st_com/en/products/development-tools/software-development-tools/stm32-software-development-tools/stm32-programmers/flasher-stm32.html)
-
-Run the **ST Flash Loader Demonstrator** program. There are many tutorials on the web on how to use this program, for example [here](http://www.scienceprog.com/flashing-programs-to-stm32-embedded-bootloader).

 ## Troubleshooting
 You can report your problem using the [GitHub issue](https://github.com/midelic/DIY-Multiprotocol-TX-Module/issues) system or go to the [Main thread on RCGROUPS](http://www.rcgroups.com/forums/showthread.php?t=2165676) to ask your question.
