-# ESP-WebOTA
+# ESP WebOTA
+
+Easily add web based [OTA](https://en.wikipedia.org/wiki/Over-the-air_programming) updates to your ESP32 projects.
+
+## Installation
+
+Clone this repo to your Arduino libraries directory. On Linux this is `~/Arduino/libraries/`
+
+## Usage
+
+Create a global variable for the Web Server:
+
+    #include <WebOTA.h>
+    WebServer OTAServer(8080);
+
+Initialize the WebOTA library at the end of your `setup()` function:
+
+    void setup() {
+        // Other init code here
+
+        init_web_ota(&OTAServer);
+    }
+
+Listen for update requests at the end of your `loop()` function:
+
+    void loop() {
+        // Other loop code here
+
+        OTAServer.handleClient();
+    }
+
+## Perform an update
+
+Navigate to your ESP32 in a web browser, typical URLs are: http://esp32-ota.local:8080/webota. To create a binary image you will need the Arduino IDE. A binary image can be created by going the `Sketch` menu and selecting `Export compiled Binary`.
