+# 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 image associated with clickable imagemap of original web links.
+
+**You are looking at a GoLang / CDP branch of WRP.**
+
+**This code is under active development and not fully usable yet.**
+
+## Done so far
+
+* basic browser-in-browser mode
+* screenshot and serve image+map via CDP
+* gif with Floyd–Steinberg dithering
+* multiple concurent client support
+* resolve relative links
+* paginated scrolling
+* google search on input not starting with ^http
+* ISMAP, although for a redirect to work `-i` flag must be specified
+  otherwise http-equiv refresh will be used and/or link provided
+* headed mode and chromedp debug output
+
+## Todo
+
+* configurable color palete and quantization
+* real http proxy support
+* padded box model coordinates
+* better http server shutdown
+
+## Old Python version
+
+Check [pywebkit/](/pywebkit) folder for the old Python-Webkit version.

+- Returns server errors as is.
+- Download non-HTML files as is.
+- For JavaScript capable browsers detect and automatically set view width.
+- Add support for configuring which image format to use.
+- Added support for PythonMagick. If found, allows to dither, color-reduce, or convert to grayscale or monochrome.
+- If PythonMagick is found, render as PNG and convert to user-requested format using it, for better quality.
+
+### Changed
+- Support www prepented to http://wrp.stop command.
+
+### Fixed
+- Prevent python crashes with non-ASCII character in URLs.
+
+## [1.4] - 2017-01-22
+### Added
+- Suport for ISMAP on Linux.
+- Use queues instead of globals in Linux.
+
+## [1.3] - 2017-01-21
+### Changed
+- Merged mac OS and Linux in a single executable.
+- Use queues instead of globals in Linux.
+
+### Fixed
+- Call PyQt to close application on http://wrp.stop
+
+## [1.2] - 2016-12-27
+### Added
+- Support for IMAP on mac OS.
+
+### Changed

+# 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.
+
+
+# Current Status
+* This is a WebKit / Python version of WRP.
+* No longer maintained / supported.
+* You should be using GoLang/CDP version instead.
+* It mostly works for casual browsing but it's not very stable.
+* Secure aka https/SSL/TLS websites might work with use of [sslstrip](https://moxie.org/software/sslstrip/) cheat (enabled by default).
+
+
+## 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. It does not work on Windows. Use Go/CDP version for that.
+
+## Installation
+* macOS - should just work
+* Linux/FreeBSD install `python-pyqt5.qtwebkit` and `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.
