 * Works as browser-in-browser. A real http proxy mode is being investigated but very unlikely to happen. Mostly because a lot of clicable elements are not http links and there is no way to proxy them. Also there is no universal way of stripping SSL that would satisfy all browsers. Check [issue #35](https://github.com/tenox7/wrp/issues/35) for more info.
 * Supports clicking on non-link elements (eg. cookie warnings, dropdown menus, etc.) and sending keystrokes. Yes, you can login to Gmail, etc.
 
-## Usage	
+## Usage
 
 1. [Download a WRP binary](https://github.com/tenox7/wrp/releases/) and run it on a machine that will become your WRP gateway server.
 2. Point your legacy browser to `http://address:port` of WRP server. Do not set or use it as a "http proxy server".
-3. Type a search string or a http/https URL and click Go.	
-4. Adjust your screen width/height/scale/#colors to fit in your old browser.

 5. Scroll web page by clicking on the in-image scroll bar.
 6. Do not use client browser history-back, instead use Bk WRP button.
 7. To send keystrokes fill K input box and press Go. There also are buttons for backspace, enter and arrow keys.

 ## History
+
 * In 2014, version 1.0 started as a cgi-bin script, adaptation of `webkit2png.py` and `pcidade.py`, [blog post](https://virtuallyfun.com/2014/03/03/surfing-modern-web-with-ancient-browsers/).
 * Later in 2014, version 2.0 became a stand alone http-proxy server, also support for both Linux/MacOS, [another post](https://virtuallyfun.com/wordpress/2014/03/11/web-rendering-proxy-update//).
 * In 2016 the whole internet migrated to HTTPS/SSL/TLS and WRP largely stopped working. Python code became unmaintainable and mostly unportable (especially to Windows, even WSL).

 * Later in 2019, WRP 4.0 has been completely refactored to use mouse clicks instead using a href nodes. Also in 4.1 added sending keystrokes in to input boxes. You can now login to Gmail. Also now runs as a Docker container.
