+## Requirements
+
+- Swift 6.1 - https://www.swift.org/install
+- ESP-IDF 5.4 - https://github.com/espressif/esp-idf
+
 ## Build
 
-ESP32-P4-Function-Ev-Board:
+### Configure build environment
+
+```shell
+source esp-idf/export.sh
+export TOOLCHAINS=$(plutil -extract CFBundleIdentifier raw /Library/Developer/Toolchains/swift-DEVELOPMENT-SNAPSHOT-2024-10-30-a.xctoolchain/Info.plist)
+```
+
+### Build for ESP32-P4-Function-Ev-Board
 
 ```shell
 idf.py @boards/esp32_p4_function_ev_board.cfg flash monitor
 ```

+### Build for ESP32-C6-DevKit
+
+![ESP32-C6-DevKit](docs/img/esp32-c6-devkit.webp)
+
+The configuration of this board is based on [ESP-BSP Generic](https://developer.espressif.com/blog/using-esp-bsp-with-devkits/) which allows configuration using menuconfig.
+
+SPI Display configuration:
+
+```ini
+CONFIG_BSP_DISPLAY_ENABLED=y
+CONFIG_BSP_DISPLAY_SCLK_GPIO=6
+CONFIG_BSP_DISPLAY_MOSI_GPIO=7
+CONFIG_BSP_DISPLAY_MISO_GPIO=-1
+CONFIG_BSP_DISPLAY_CS_GPIO=20
+CONFIG_BSP_DISPLAY_DC_GPIO=21
+CONFIG_BSP_DISPLAY_RST_GPIO=3
+CONFIG_BSP_DISPLAY_DRIVER_ILI9341=y
+```
+
+You can change the configuration by running:
+
+```shell
+idf.py @boards/esp32_c6_devkit.cfg menuconfig
+```
+
+```shell
+idf.py @boards/esp32_c6_devkit.cfg flash monitor
