-# N2CMU
+# N2CMU (Neural Network Coprocessing Microcontroller Unit)
 
-Neural Network Coprocessing Microcontroller Unit (via UART) for STM32F103C8T6 Bluepill Devboard written in TinyGo.
+N2CMU is a project aimed at implementing a neural network coprocessing microcontroller unit (MCU) for STM32F103C8T6 Bluepill development board using the TinyGo (Go programming language for embedded systems). This MCU enables offloading feedforward neural network computations to a dedicated hardware unit, allowing for efficient and low-power feedforward neural network training and inference on small hardware embedded systems.
+
+## Features
+
+- **Neural Network Coprocessing**: N2CMU allows offloading feedforward neural network computations to a dedicated coprocessing unit, freeing up the main microcontroller for other tasks.
+- **UART Communication**: Communication with N2CMU is facilitated via UART, enabling external devices to control and interact with the coprocessing unit.
+- **Flexible Configuration**: N2CMU supports dynamic configuration of neural network parameters such as input, hidden, and output neuron counts, as well as weights, biases, and gradients.
+- **Training and Inference**: The coprocessing unit supports both training and inference modes, allowing for the optimization of neural network models directly on the microcontroller.

+## Getting Started
+
+### Prerequisites
+
+To run N2CMU on your STM32F103C8T6 Bluepill development board, you'll need:
+
+1. STM32F103C8T6 Bluepill development board
+2. ST-Link v2
+3. [TinyGo compiler](https://tinygo.org/getting-started/install/)
+4. [Qrepo](https://github.com/nthnn/Qrepo) package manager
+
+### Installation
+
+1. Clone the N2CMU repository to your local machine:
+
+```bash
+git clone https://github.com/nthnn/n2cmu.git
+```
+
+2. Connect your STM32F103C8T6 Bluepill development board to your computer using a USB to UART converter.
+
+3. Flash the code to your STM32F103C8T6 Bluepill development board using your ST-Link v2:
+
+```bash
+cd n2cmu
+qrepo run flash
+```
+
+4. You're now ready to interact with N2CMU and start utilizing its neural network coprocessing capabilities. Follow the example schematic below for Arduino UNO (but other boards will do).
