+Do this in a Python 3.5+ environment::
 
-  $ pip install mitmproxy-HTTPolice

 To run HTTPolice together with mitmproxy, use a command like this::
 
-  $ mitmdump -s "`python -m mitmproxy_httpolice` -o html report.html"
+  $ mitmdump -s "`python3 -m mitmproxy_httpolice` -o html report.html"
 
 Note the backticks.
 Also, you can replace ``mitmdump`` with ``mitmproxy`` if you wish.
 
 ``-s`` is an option for mitmproxy that specifies an inline script to run,
 along with arguments to that script.

 mitmproxy/mitmdump itself has many interesting options.
 One of the more useful features is the ability to dump traffic into a file.
 If you do this, you can then “replay” it as many times as you wish::
