-WRP is a HTTP proxy service that renders the web page in to a GIF/JPEG image associated with clickable imagemap of the original web links. It allows to use historical and obsolete web browsers on the modern web. It's still a work in progress but it's quite stable and usable for casual web browsing.
-
-Two versions of WRP exist, Cocoa-Webkit for Mac OS X and QT-Webkit, for Linux, BSD and other platforms.

+# WRP - Web Rendering Proxy
+A HTTP proxy server that allows to use historical and obsolete web browsers on the modern web. It works by rendering the web page in to a GIF/PNG/JPEG image associated with clickable imagemap of original web links. 
+
+New: Version 2.1 brings support for sslstrip to allow browsing https/SSL/TSL websites
+
+
+# Current Status
+* SSL/TLS stripping is delegated to `sslstrip`[1], which you need to install into your PATH first
+* I'm also looking for moving away from WebKit, QT and Python
+* Stay tuned
+
+## OS Support
+WRP works on macOS (Mac OS X), Linux and FreeBSD. On macOS it uses Cocoa Webkit, on Linux/FreeBSD QT Webkit, for which needs PyQT4 or PyQT5.
+
+## Installation
+* macOS - should just work
+* Linux/FreeBSD install `python-pyqt5.qtwebkit`
+* For sslstrip install `sslstrip`
+* For PythonMagick (Imagemagick library) install `python-pythonmagick`
+
+## Configuration
+Edit wrp.py, scroll past Copyright section to find config parameters
+
+## Usage 
+Configure your web browser to use HTTP proxy at IP address and port where WRP is running. If using browsers prior to HTML 3.2, ISMAP option may need to be enabled. Check configuration.
