+Weather display example
+=======================================
+
+This is **port of project https://github.com/G6EJD/ESP32-e-Paper-Weather-Display by David Bird 2018** to work with ED097OC4 Kindle display and this driver.
+**Please note that David Bird (https://github.com/G6EJD) owns the copyright to this software!** Only minor modifications where made for it to run with the epdiy driver.
+THe  license details are outlined in **License.txt**.
+
+Building It
+-----------
+
+ - Girst you need to install Arduino esp-idf as a component https://github.com/espressif/arduino-esp32/blob/master/docs/esp-idf_component.md (the easiest way is to put it into components folder of ESP-IDF)
+ - Put Arduino JSON https://github.com/bblanchon/ArduinoJson into components/arduino/
+ - Dont forget to insert your Wi-Fi settings and openweathermap API key into owm_credentials.h
+ - If you want to add more fonts, firmware may not fit into 1M and easiest way to fix it is to edit components/partition_table/partitions_singleapp.csv and change 1M to 2M
