-## Minimal example of WebsocketClientOTA and Python server
-
-Take this as small example, how achieve OTA update on ESP8266 and ESP32.
-
-Python server was wrote from train so take it only as bare example.
-It's working, but it's not mean to run in production.
-
-
-### Usage:
-
-Start server:
-```bash
-cd python_ota_server
-python3 -m venv .venv
-source .venv/bin/activate
-pip3 install -r requirements.txt
-python3 main.py
-```
-
-Flash ESP with example sketch and start it.
-
-Change version inside example sketch to higher and compile it and save it to bin file.
-
-Rename it to `mydevice-1.0.1-esp8266.bin` and place it inside new folder firmware (server create it).
-
-When the ESP connect to server, it check if version flashed is equal to fw in firmware folder. If higher FW version is present,
-start the flash process.
