+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You

+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must

+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed

+          notices within Derivative Works that You distribute, alongside

+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions

+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or

+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+# 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.

+# 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.
+
+## More info and screenshots
