 ***DEVELOPMENT FOR THIS PROJECT TAKES PLACE ON THE `canalyzer` BRANCH***
 
-CANalyzer will be a terminal-based CAN bus analyzer tool designed to run on Linux. It will utilize `ncurses` for a text-based terminal user interface and `socketcan` to interface with the CAN bus.
+CANalyzer will be a custom CAN bus analyzer tool device. The end-goal is to have a fully embedded
+device that can be used to monitor and log CAN bus traffic. Its main inspiration is the PEAK System
+[diagnostic tool](https://www.peak-system.com/PCAN-Diag-FD.456.0.html?&L=1). Custom hardware will
+be designed by EHW in parallel with the software development.
+
+In order to get a prototype up and running quickly, we will begin software development with a
+Linux based application. It will utilize `ncurses` for a text-based terminal user interface and
+`socketcan` to interface with the CAN bus.
