+ESCape32 Wi-Fi Link
+===================
+
+ESP32-based embedded configurator for [ESCape32](https://github.com/neoxic/ESCape32) electronic speed controllers.
+
+
+Installation
+------------
+
+Download the latest pre-built combined image [here](https://github.com/neoxic/ESCape32-WiFi-Link/releases).
+
+Flash your board using the [ESP Flash Tool](https://www.espressif.com/en/support/download/other-tools) or any DFU utility, e.g. dfu-util.
+
+Visit the [ESCape32 Wiki / Wi-Fi Link](https://github.com/neoxic/ESCape32/wiki/WiFiLink) page for more information.
+
+
+Pinouts
+-------
+
+|    MCU   | RX | TX | LED |
+|----------|---:|---:|----:|
+| ESP32-C3 |  4 |  2 |  *8 |
+| ESP32-S2 | 16 | 33 |  15 |
+
+(*) active low
+
+_Note:_ The above GPIO pin numbers can be changed using the `idf.py menuconfig` command.
+
+
+Building from source
+--------------------
+
+Install the ESP-IDF environment as described [here](https://idf.espressif.com).
+
+To build for the ESP32-S2, run:
+
+```
+idf.py set-target esp32s2
+idf.py build
+```
+
+To install on the device, run:
+
+```
+idf.py flash
+```
+
+To make a combined image, run:
+
+```
+cd build
+esptool.py --chip esp32s2 merge_bin -o ESCape32-WiFi-Link-ESP32-S2.bin @flash_args
+```
