+### VK Image
+
+<sup>[API method description.](https://2captcha.com/2captcha-api#vkcaptcha)</sup>
+
+We offer two methods to solve this type of captcha - token-based and image-based.
+
+We use the body (image in base64 format) or file (image as file) and steps parameters.
+You can get both values from the response to the request https://api.vk.com/method/captchaNotRobot.getContent?v={API_VER} when loading the captcha widget on the page.
+
+```java
+VkCaptcha captcha = new VkCaptcha("vkimage");
+captcha.setImageBase64(base64EncodedImage);
+captcha.setSteps("[5,12,22,24,21,23,10,7,2,8,...]");
+```
+### VK Captcha
+
+<sup>[API method description.](https://2captcha.com/2captcha-api#vk-captcha)</sup>
+
+Token-based method requires redirect_uri parameter, as well as proxy and userAgent. The value of the redirect_uri parameter can be found in the response to requests to the VK API that return captchas.
+
+```java
+VkCaptcha captcha = new VkCaptcha("vkcaptcha");
+captcha.setRedirectUri("https://id.vk.com/not_robot_captcha?domain=vk.com&session_token=eyJ....HGsc5B4LyvjA&variant=popup&blank=1");

+captcha.setProxy("http", "1.2.3.4");
