 ## Installation 
 
 Compile and upload to clock using the `elekstube_ips` PlatformIO environment
-Once uploaded (the clock can be flashed like any ESP32 module), go to `[WLED-IP]/edit` and upload the 0-9.bmp files from the bmp folder.
-Use LED pin 12, relay pin 27 and button pin 34.
+Once uploaded (the clock can be flashed like any ESP32 module), go to `[WLED-IP]/edit` and upload the 0-9.bin files from [here](https://github.com/Aircoookie/NixieThemes/tree/master/themes/RealisticNixie/bin).
+You can find more clockfaces in the [NixieThemes](https://github.com/Aircoookie/NixieThemes/) repo.
+Use LED pin 12, relay pin 27 and button pin 34.

+## Use of RGB565 images
+
+Binary 16-bit per pixel RGB565 format `.bin` images are now supported. This has the benefit of only using 2/3rds of the file size a `.bmp` has.
+The drawback is that this format cannot be handled by common image programs and that an extra conversion step is needed.
+You can use https://lvgl.io/tools/imageconverter to convert your .bmp to a .bin file (settings `True color` and `Binary RGB565`)
+Thank you to @RedNax67 for adding .bin support.
