+# Twinleaf I/O Tools in Rust
+
+This repository contains a set of tools that are useful for working with Twinleaf quantum sensors and accessories. 
+
+The primary tool is the proxy, which makes the device available via ethernet:
+
+		tio-proxy --auto
+
+When there are more than one serial port available, it is necessary to specify the port
+
+		[linux]> tio-proxy -r /dev/ttyACM0
+		[macOS]> tio-proxy -r /dev/cu.usbserialXXXXXX
+		[wsl1] > tio-proxy -r COM3
+
+With the proxy running, a set of tools can be used on the data stream. 
+
+Logging data:
+
+		tio-tool log
+
+Issuing commands:
+
+		tio-tool rpc dev.name
+
+And a variety of additional useful functions.
+
+
+## Installation
+
+On macOS and linux, there is a dependency on libudev; to install it use:
+
+		sudo apt install libudev-dev  # debian linux
+		brew install libudev          # macOS homebrew
+
+Now build:
+
+		cargo build --release
+
+The resulting tools can be found in the target directory:
+
+		cd target/release
+		./tio-tool
+
+## Cross compilation 
+
+The tools can be compiled for other platforms by first adding those platform targets:
+
+		rustup target add x86_64-pc-windows-gnu
+		rustup toolchain install stable-x86_64-pc-windows-gnu
+
+And then building for the new target:
+
+		cargo build --target x86_64-pc-windows-gnu
