+Usage
+=====
+**⚠️IMPORTANT⚠️**: To bypass the nhentai frequency limit, you should use `--cookie` and `--useragent` options to store your cookie and your user-agent.
+
+*The default download folder will be the path where you run the command (CLI path).*
+
+
+Set your nhentai cookie against captcha:
+
+.. code-block:: bash
+
+    nhentai --useragent "USER AGENT of YOUR BROWSER"
+    nhentai --cookie "YOUR COOKIE FROM nhentai.net"
+
+**NOTE**
+
+- The format of the cookie is `"csrftoken=TOKEN; sessionid=ID; cf_clearance=CLOUDFLARE"`
+- `cf_clearance` cookie and useragent must be set if you encounter "blocked by cloudflare captcha" error. Make sure you use the same IP and useragent as when you got it
+
+| To get csrftoken and sessionid, first login to your nhentai account in web browser, then:
