+
+## Building the Turbo decode/encode executables
+
+1. Open the Cygwin terminal (should be on your desktop, search the start menu if not)
+2. Navigate to where you have extracted/cloned the `dji_droneid` repo in Windows
+   If you have the code at `C:\Users\<user_name>\Downloads\dji_droneid` then you would run: `cd /cygdrive/c/Users/<user_name>/Downloads/dji_droneid` in the Cygwin terminal
+3. Run the following set of commands in the Cygwin terminal
+```
+pushd cpp
+wget https://raw.githubusercontent.com/d-bahr/CRCpp/master/inc/CRC.h -O CRC.h
+mkdir -p deps; pushd deps
+git clone https://github.com/ttsou/turbofec; pushd turbofec
+autoreconf -i && ./configure && make && make install
+popd && popd
+g++ -Wall add_turbo.cc -o add_turbo -I. -I/usr/local/include -L/usr/local/lib -lturbofec
+g++ -Wall remove_turbo.cc -o remove_turbo -I. -I/usr/local/include -L/usr/local/lib -lturbofec
+```
+
+You should now have two new executables: `add_turbo` and `remove_turbo`
+
+These executables should be usable from Windows
