+Refer to the [OpenTX wiki](https://github.com/opentx/opentx/wiki) for information about setting up a tool chain for building OpenTX and other development/developer related topics.
+
+### Installation
+
+Installation largely follows the installation of OpenTx 2.3.15. It involves three steps:
+
+1. Flash the mTX firmware binary appropriate for your radio to the radio. You can follow the standard OpenTx descriptions, except that you choose a different binary file. A convenient method for flashing can be using the OpenTx Companion.
+2. Copy the SD content required for OpenTx 2.3.15 to the radio's SD card. Follow the OpenTx descriptions for this step.
+3. Copy the SD card content provided in the SDCARD folder to the radio's SD card.
