+# Example Server with mCaptcha protection
+
+The example server shows a dummy form with the mCaptcha widget. When the
+form is submitted, it validates the [authorization
+token](https://mcaptcha.org/docs/webmasters/terminology#authorization-token)
+presented by the visitor against the mCaptcha instance that the server
+is configured with.
+
+The example server is built with Express (JavaScript) webframework and
+uses the [JavaScript API library for
+mCaptcha](https://www.npmjs.com/package/@mcaptcha/mcaptcha-api-js) for
+validation.
+
+## 1. Configuration
+
+Before running, please configure the server:
+
+```bash
+cp .env_sample .env
+```
+
+And fill in the configuration parameters in `.env` file with:
+
+1. [Sitekey](https://mcaptcha.org/docs/webmasters/terminology#sitekey)
+2. Account secret: Available in the settings page on the mCaptcha
+   dashboard
+3. Instance URL
+
+## 2. Install dependencies
+
+Tested with Node v20.
+
+```bash
+npm install
+```
+
+## 3. Launch server
+
+```bash
+node src/index.js
+```
+
+If all configuration parameters are properly filled in, the example server must
+work.
