 ## <a id="docIntro"></a>Introduction
 
-SSL traffic poses a potential problem when using mitmproxy, as it is encrypted, it is opaque to inspection.  In order to be able to decrypt the traffic, you must use a certificate that the client, whose traffic you are intercepting, trusts.  This document outlines the different options you have for either using the certificate that mitmproxy generates or using your own.
+Mitmproxy can decrypt encrypted traffic on the fly, as long as the client
+trusts its built-in certificate authority. Usually this means that the
+mitmproxy CA certificates have to be installed on the client device.
 
 ## <a id="docQuick"></a>Quick Setup
 
-By far the easiest way to install the mitmproxy certificates is to use the built-in web app. To do this, start mitmproxy and configure your target device with the correct proxy settings. Now start a browser on the device, and visit the domain **mitm.it**.

-Certificates are installed via several different methods depending on the client.  There are too many to go into in this document, consult the documentation for the client that you would to have trust the mitmproxy root certificate, for specific installation instructions.
 
 ## <a id="docManual"></a>Installing the mitmproxy CA certificate manually
 
-Most of the time you can easily install mitmproxy's CA certificate through the webapp, and just follow the prompts.  In a couple of situations, such as Java or the iOS Simulator, there aren't any obvious ways to install the CA certificate.
+Sometimes using the quick install app is not an option - Java or the IOS
+similator spring to mind - or you just need to do it manually for some other
+reason. Below is a list of pointers to manual certificate installation
+documentation for some common platforms:

-The first time __mitmproxy__ or __mitmdump__ is run, the mitmproxy Certificate Authority(CA) is created in the config directory (~/.mitmproxy by default).  This CA is used for on-the-fly generation of dummy certificates for each of the SSL sites that your client visits. Since your browser won't trust the __mitmproxy__ CA out of the box , you will see an SSL certificate warning every time you visit a new SSL domain through __mitmproxy__. When you are testing a single site through a browser, just accepting the bogus SSL cert manually is not too much trouble, but there are a many circumstances where you will want to configure your testing system or browser to trust the __mitmproxy__ CA as a signing root authority.
