+Style Guide & Running Tests
+---------------------------
+
+We use `flake8`__ for checking style requirements and `nosetests`__ to run Catalyst tests. Our `continuous integration`__ tool will run these commands.
+
+__ http://flake8.pycqa.org/en/latest/
+__ http://nose.readthedocs.io/en/latest/
+__ https://en.wikipedia.org/wiki/Continuous_integration
+
+Before submitting patches or pull requests, please ensure that your changes pass when running:
+
+.. code-block:: bash
+
+   $ flake8 catalyst tests
+
+In order to run tests locally, you'll need to install several libraries
+(one of them is TA-lib, so make sure you have it installed following `these instructions`__ before continuing).
+
+__ https://mrjbq7.github.io/ta-lib/install.html
+
+.. code-block:: bash
+
+   $ pip install -r ./etc/requirements.txt
+   $ pip install -r ./etc/requirements_dev.txt
+   $ pip install -r ./etc/requirements_blaze.txt
+   $ pip install -r ./etc/requirements_talib.txt
+   $ pip install -e .
+
+You should now be free to run tests:
+
+.. code-block:: bash
+
+   $ cd tests && nosetests
+
+
+Continuous Integration
+----------------------
+
+We use `Travis CI`__ for Linux-64 bit builds.
+
+.. note::
+
+   We do not currently have CI for OSX-64 bit builds or Windows-64 bit builds.
