+OTA firmware uploading
+----------------------
+
+There are 2 options:
+
+* Directly specify :option:`platformio run --upload-port` in command line
+
+.. code-block:: bash
+
+    platformio run --target upload --upload-port IP_ADDRESS_HERE
+
+* Specify ``upload_port`` option in :ref:`projectconf`
+
+.. code-block:: ini
+
+   [env:***]
+   ...
+   upload_port = IP_ADDRESS_HERE
+
+Authentication and upload options
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+You can pass additional options/flags to OTA uploader using
+``upload_flags`` option in :ref:`projectconf`
+
+.. code-block:: ini
+
+    [env:***]
+    upload_flags = --port=8266
+
+Availalbe flags
+
+* ``--port=ESP_PORT`` ESP8266 ota Port. Default 8266
+* ``--auth=AUTH`` Set authentication password
+* ``--spiffs`` Use this option to transmit a SPIFFS image and do not flash
+  the module
+
+For the full list with availalbe options please run
+
+.. code-block:: bash
+
+    ~/.platformio/packages/framework-arduinoespressif/tools/espota.py -h
+
+    Usage: espota.py [options]
+
+    Transmit image over the air to the esp8266 module with OTA support.
+
+    Options:
+      -h, --help            show this help message and exit
+
+      Destination:
+        -i ESP_IP, --ip=ESP_IP
+                            ESP8266 IP Address.
+        -p ESP_PORT, --port=ESP_PORT
+                            ESP8266 ota Port. Default 8266
+
+      Authentication:
+        -a AUTH, --auth=AUTH
+                            Set authentication password.
