+If you are wondering which howto guide you should follow:
+
+Generally, the guides named '*-managed-*.txt" are easier to follow,
+and they require a tor version newer than 0.2.3.11.
+
+If you have an older version of tor, you can use the guides named
+"*-external-*.txt".

+How to set up Tor Client with obfsproxy
+=======================================
+
+[1] You will need:
+
+* a copy of obfsproxy:
+  git clone git://git.torproject.org/obfsproxy.git
+  Build it with: "./autogen.sh && ./configure && make".
+  You will need libevent-2 to build it.
+
+* a copy of Tor that supports the ClientTransportPlugin option.
+  Any Tor version newer than 0.2.3.2 will do the trick.
+
+[2] Set up obfsproxy:
+
+This command will setup an obfsproxy client speaking the obfs2
+protocol:
+
+./obfsproxy obfs2 socks 127.0.0.1:1050
+
+[3] Set up tor:
+
+You should put the following lines in your torrc file:
+---
+SocksPort 5000
+UseBridges 1
+Bridge obfs2 <bridge address>:1051 # This is provided by the bridge operator.
+ClientTransportPlugin obfs2 socks5 127.0.0.1:1050
+---
+substituting <bridge address> with the IP address of your bridge
+relay.
+
+[4] Done!
+
+Now to test it, launch Firefox and set it up to use a Socks server on
+127.0.0.1:5000. Now browse the web.

+* a copy of Tor that supports the managed ClientTransportPlugin
+  option. The current git master should work.
+
+[2] Set up tor:
+
+You should put the following lines in your torrc file:
+"""
+SocksPort 5000
+UseBridges 1
+Bridge obfs2 <bridge address>:1051 # This is provided by the bridge operator.
+ClientTransportPlugin obfs2 exec <path to obfsproxy> --managed
+"""
+where <path to obfsproxy> is the path to the obfsproxy executable. If
+you successfuly compiled obfsproxy, the executable should be in the
+obfsproxy directory.
+
+[3] Done!
+
+To test it, launch Firefox and set it up to use a SOCKS server on
+127.0.0.1:5000. Now browse the web.

+How to Set up a Tor Bridge with obfsproxy
+=========================================
+
+[1] You will need:
+
+* a copy of obfsproxy:
+  git clone git://git.torproject.org/obfsproxy.git
+  Build it with: "./autogen.sh && ./configure && make".
+  You will need libevent-2 to build it.
+
+* a copy of Tor that can be configured as a bridge.
+
+[2] Set up obfsproxy:
+
+This command will setup an obfsproxy server speaking the obfs2
+protocol:
+
+./obfsproxy obfs2 --dest=127.0.0.1:5001 server 0.0.0.0:1051
+
+Be sure to pass the value of ORPort of your bridge relay to the --dest
+argument (see next section). In this example, we assumed it was '5001'.
+
+[3] Set up tor:
+
+You should put the following lines in your torrc file:
+---
+ORPort 5001
+BridgeRelay 1
+ExitPolicy reject *:*
+---
+
+[4] Done!
+
+Now, instruct censored people to connect to your IP on port 1051. So,
+for example, if your bridge's address is 192.0.2.42, bridge users
+should connect to 192.0.2.42:1051.
+
+During the above process, you can use any port numbers you want, but
+make sure to adjust the torrc and obfsproxy commands accordingly.
+
+Finally, don't forget that you might also need to set up port
+forwarding.

+"""
+ORPort 5001 # Port on which bridge will be listening on.
+BridgeRelay 1
+ExitPolicy reject *:*
+ServerTransportPlugin obfs2 exec <path to obfsproxy> --managed
+"""
+
+[3] Launch tor
+
+Now launch tor and monitor your logs.
+You should see a message similar to:
+
+"[warn] Registered server transport 'obfs2' at '0.0.0.0:33578'"
+
+note down the port number ('33578' in this case). It's the port number
+that you should tell your bridge clients to use.
+
+[4] Done!
+
+Now, instruct censored people to connect to your IP on the port you
+found in the previous step (e.g 33578).  So, for example, if your
+bridge's address is 192.0.2.42, bridge users should connect to
+192.0.2.42:33578.
+
+Tor will try to always spawn your transport proxy at the same port, so
+you won't have to do this procedure in every Tor restart.
+
+Finally, don't forget that you might also need to set up port
+forwarding.

-How to set up Tor with obfsproxy
-================================
-
-        Instructions:
-
-       "I AM A CENSORED FELLOW"
-
-[1] You will need:
-
-* a copy of obfsproxy:
-  git clone git://git.torproject.org/obfsproxy.git
-  Building it should be easy, just do "./configure && make".
-
-* a copy of Tor that supports the Socks5Proxy option.
-  Tor 0.2.2.30 - for example - will work.
-
-[2] Set up obfsproxy:
-
-This command will setup an obfsproxy client speaking the obfs2
-protocol on localhost:1050:
-
-./obfsproxy obfs2 socks 127.0.0.1:1050
-
-[3] Set up tor:
-
-You should put in your torrc file:
----
-SocksPort 5000
-UseBridges 1
-Bridge <bridge address>:1051 # This is provided by the bridge operator.
-Socks5Proxy 127.0.0.1:1050 # This points to the obfsproxy client.
----
-
-Of course you should substitute the value of the Bridge line above,
-with the information provided to you by a bridge operator.
-
-[4] Done!
-
-Alright, you are done!
-Make sure you have followed the above steps on the correct order:
-First launch obfsproxy and then launch tor.
-
-Now to test it, launch Firefox and set it up to use a Socks server on
-127.0.0.1:5000. Now browse the web.
-
-
-        "I AM A BRIDGE OPERATOR THAT WANTS TO HELP CENSORED PEOPLE"
-
-[1] You will need:
-
-* a copy of obfsproxy:
-  git clone git://git.torproject.org/obfsproxy.git
-  Building it should be easy, just do "./configure && make".
-
-* a copy of Tor which can function as a Tor bridge.
-
-[2] Set up obfsproxy:
-
-This command will setup an obfsproxy server speaking the obfs2
-protocol on localhost:1051:
-
-./obfsproxy obfs2 --dest 127.0.0.1:5001 server 127.0.0.1:1051
-
-Be sure to pass the value of ORPort of your bridge relay to the --dest
-argument (see next section).
-
-[3] Set up tor:
-
-You should put in your torrc file:
----
-ORPort 5001 # Port on which bridge will be listening on.
-BridgeRelay 1
-ExitPolicy reject *:*
----
-
-[4] Done!
-
-Make sure you have followed the above steps on the correct order.
-First launch obfsproxy and then launch tor.
-You can use any port numbers you want, just be sure to adjust the
-torrc and obfsproxy commands accordingly.
-
-Don't forget that You might need to set up port forwarding.
-
-Now you should tell censored people to connect to your IP on port 1051.
-So, for example, if your bridge's address is 85.22.13.1, bridge users
-should connect to 85.22.13.1:1051.
-Pay attention that '1051' is the port where obfsproxy is listening on,
-and *not* your bridge's ORPort.
