+ * A {@link WebDriver} implementation that controls a Blink-based Opera browser running on the local
+ * machine. It requires an <code>operadriver</code> executable to be available in PATH.
+ *
+ * @see <a href="https://github.com/operasoftware/operachromiumdriver">operadriver</a>
+ * 
+ * Since operadriver does not support w3c, Selenium will remove the support in the next version.
+ * @deprecated Use {@link org.openqa.selenium.chrome.ChromeDriver} with
+ * {@link org.openqa.selenium.chrome.ChromeOptions#setBinary(File)} or {@link org.openqa.selenium.chrome.ChromeOptions#setBinary(String)}
+ * to set the path to the Opera browser.
+ *
+ * <p>Example usage:
+ * <pre><code>
+ * ChromeOptions options = new ChromeOptions()
+ * options.setBinary(new File("/path/to/opera"));
+ *
+ * // For using Opera browser with ChromeDriver:
+ * ChromeDriver driver = new ChromeDriver(options);
+ *
+ * // For use with RemoteWebDriver:
+ * ChromeOptions options = new ChromeOptions();
+ * options.setBinary(new File("/path/to/opera"));
