-Hacking
--------
+As an open source project, mitmproxy welcomes contributions of all forms. If you would like to bring the project forward,
+please consider contributing in the following areas:
 
-To get started hacking on mitmproxy, make sure you have Python_ 3.5.x or above with
-virtualenv_ installed (you can find installation instructions for virtualenv
-`here <http://virtualenv.readthedocs.org/en/latest/>`__). Then do the following:
+- **Maintenance:** We are *incredibly* thankful for individuals who are stepping up and helping with maintenance. This includes (but is not limited to) triaging issues, reviewing pull requests and picking up stale ones, helping out other users in our forums_, creating minimal, complete and verifiable examples or test cases for existing bug reports, updating documentation, or fixing minor bugs that have recently been reported.
+- **Code Contributions:** We actively mark issues that we consider are `good first contributions`_. If you intend to work on a larger contribution to the project, please come talk to us first.

+Development Setup
+-----------------
+
+To get started hacking on mitmproxy, please follow the `advanced installation`_ steps to install mitmproxy from source, but stop right before running ``pip3 install mitmproxy``. Instead, do the following:
 
 .. code-block:: text
 
-    sudo apt-get install python3-pip python3-dev libffi-dev libssl-dev libtiff5-dev libjpeg8-dev zlib1g-dev libwebp-dev

+and install all mandatory and optional dependencies into it. The primary
+mitmproxy components - mitmproxy and pathod - are installed as
 "editable", so any changes to the source in the repository will be reflected
 live in the virtualenv.
 
-To confirm that you're up and running, activate the virtualenv, and run the
-mitmproxy test suite:
-
-.. code-block:: text
-
-    . venv3.5/bin/activate  # venv\Scripts\activate on Windows
-    py.test

+The main executables for the project - ``mitmdump``, ``mitmproxy``,
 ``mitmweb``, ``pathod``, and ``pathoc`` - are all created within the
 virtualenv. After activating the virtualenv, they will be on your $PATH, and
 you can run them like any other command:
 
 .. code-block:: text
 
+    . venv/bin/activate  # "venv\Scripts\activate" on Windows
     mitmdump --version
 
-For convenience, the project includes an autoenv_ file (`.env`_) that
-auto-activates the virtualenv when you cd into the mitmproxy directory.

 Testing
 -------
 
 If you've followed the procedure above, you already have all the development
-requirements installed, and you can simply run the test suite:
+requirements installed, and you can run the full test suite (including tests for code style and documentation) with tox_:
 
 .. code-block:: text
 
-    py.test

+
+For speedier testing, we recommend you run `pytest`_ directly on individual test files or folders:
+
+.. code-block:: text
+
+    cd test/mitmproxy/addons
+    pytest --cov mitmproxy.addons.anticache --looponfail test_anticache.py
+
