 # ESP32 Zephyr RTOS Watch
 
-**Supported Boards:**
+This is a smart-watch project based on ESP32, LVGL and Zephyr RTOS. I started it as a side project to learn about Zephyr, BLE and LVGL. As you can imagine, it was a big kick to learn about many stuff at oonce. Now, I'm proud to present you. Feel free to contribute and/or contact to me!
+
+### Features
+- LVGL for UI and Graphics Rendering
+- BLE Current Time Service (GATT) for Time Synchronization
+- BLE Device Information Service (DIS) for Device Metadata
+
+### Supported Boards
 - [ESP32-S3-Touch-LCD-1.28](https://www.waveshare.com/wiki/ESP32-S3-Touch-LCD-1.28)
 
-## Build Instructions
+## Tools
+We created another repository called [ZephyrWatchBLETools](https://github.com/electricalgorithm/ZephyrWatchBLETools) to publish all the utilities needed to use ZephyrWatch. Currently, the list is very limited, however, I plan to expand it in the future.
+
+- updatetime.py: A script to synchronize the time on the ZephyrWatch with the computer's time.
+
+
+## Build
 1. Install the Zephyr according the information in their website.
 2. Get the ESP32 HAL using `west blobs fetch hal_espressif`.
 3. Clone the package and build it using the instructions provided.
