+# Vehicle Control Unit (VCU) Firmware and Model
+
+The Vehicle Control Unit (VCU) manages the car's state and rules requirements. It also manages the entire torque path between
+digitized driver pedal inputs and outputs.
+
+VCU Firmware will live in the `VCU/Firmware` directory, while the model files will be located in the `VCU/Model` directory.
+
+This directory can be recursively built by running `bazel build //VCU/...`. Additionally, the generated files will be placed in the `bazel-bin/VCU/` directory.
+
+The firmware target is `//VCU/Firmware:vcu_firmware_2026`.
+
+Model firmware target: `//VCU/Model:vcu_model_2026`.
