We assume you have already [installed]({{< relref "/overview/installation">}}) mitmproxy on your machine.
You can start any of our three tools from the command line / terminal.
Mitmproxy starts as a [regular HTTP proxy]({{< relref
"/concepts/modes#regular-proxy">}}) by default and listens on http://localhost:8080.
You need to configure your browser or device to route all traffic through mitmproxy. Browser versions and configurations options frequently change, so we recommend to simply search the web on how to configure an HTTP proxy for your system. Some operating system have a global settings, some browser have their own, other applications use environment variables, etc.
You can check that your web traffic is going through mitmproxy by browsing to http://mitm.it - it should present you with a [simple page]({{< relref "/concepts/certificates#quick-setup">}}) to install the mitmproxy Certificate Authority - which is also the next step. Follow the instructions for your OS / system and install the CA.
At this point your running mitmproxy instance should already show the first HTTP flows from your client. You can test that all TLS-encrypted web traffic is working as expected by browsing to https://mitmproxy.org - it should show up as new flow and you can inspect it.
