+
+Minor modifications made by Mario Vilas (http://breakingcode.wordpress.com/)
+mainly to merge bug fixes found in Sourceforge
+
+Modifications made by Anorov (https://github.com/Anorov)
+-Forked and renamed to PySocks
+-Fixed issue with HTTP proxy failure checking (same bug that was in the old ___recvall() method)
+-Included SocksiPyHandler (sockshandler.py), to be used as a urllib2 handler,
+ courtesy of e000 (https://github.com/e000): https://gist.github.com/869791#file_socksipyhandler.py
+-Re-styled code to make it readable
+    -Aliased PROXY_TYPE_SOCKS5 -> SOCKS5 etc.
+    -Improved exception handling and output
+    -Removed irritating use of sequence indexes, replaced with tuple unpacked variables
+    -Fixed up Python 3 bytestring handling - chr(0x03).encode() -> b"\x03"
+    -Other general fixes
+-Added clarification that the HTTP proxy connection method only supports CONNECT-style tunneling HTTP proxies
+-Various small bug fixes

-## Proxy Lists
-To use proxy lists, navigate to `api/secret/proxies/` and create the following files:
-- `http.txt`
-- `socks4.txt`
-- `socks5.txt`
-
-Then, paste your proxies in the following format:
-
-```
-[username:password@]host:port
-```
-
-e.g.
-
-```
-1.2.3.4:8080
-user:pass@127.0.0.1:1337
-```
-
-You can use comments just like in Python.

-**Important:** to use the proxy lists, you need to change the `USE_PROXY_LIST` environment variable to `True`!
