+# ESP-Hosted Firmware
+
+Pre-built [ESP-Hosted-MCU](https://github.com/espressif/esp-hosted-mcu) co-processor firmware binaries
+
+## Overview
+
+The slave firmware enables host MCUs to utilize the Wi-Fi and Bluetooth capabilities of ESP32 series chips through **SDIO, SPI, or UART** interfaces.
+
+## Supported Co-processors and Transports
+
+The following table summarizes the supported co-processors and transport communication buses between the slave and host.
+
+| Transport Supported | SDIO | SPI Full-Duplex | SPI Half-Duplex | UART |
+|---|:---:|:---:|:---:|:---:|
+| **Co-Processors Supported** | | | | |
+| ESP32 | ✓ | ✓ | × | ✓ |
+| ESP32-C2 | × | ✓ | ✓ | ✓ |
+| ESP32-C3 | × | ✓ | ✓ | ✓ |
+| ESP32-C5 | ✓ | ✓ | ✓ | ✓ |
+| ESP32-C6/C61 | ✓ | ✓ | ✓ | ✓ |
+| ESP32-S2 | × | ✓ | ✓ | ✓ |
+| ESP32-S3 | × | ✓ | ✓ | ✓ |
+
+## Usage
+
+Download the appropriate firmware binary for your co-processor from the [Releases](https://github.com/pioarduino/esp-hosted-mcu-firmware/releases) page
+
+## Building Locally
+
+To build the firmware locally:
+
+```bash
+# Clone ESP-IDF
+git clone -b v5.5.1 --recursive https://github.com/espressif/esp-idf.git
+cd esp-idf
+./install.sh esp32c6  # or your target
+source export.sh
+cd ..
+
+# Create project from ESP-Hosted example
+idf.py create-project-from-example "espressif/esp_hosted==2.7.3:slave"
+cd slave/
+
+# Build for your target
+idf.py set-target esp32c6  # or your target
+idf.py build
+
+# Output: build/network_adapter.bin
+```
+
+## Versioning
+
+Releases are tagged with the ESP-Hosted-MCU version used (e.g., `v2.7.3`).
