 Thanks for reading this, all contributions are very much welcome!
 
-Please be aware that ``fbchat`` uses `Scemantic Versioning <https://semver.org/>`__
+Please be aware that ``fbchat`` uses `Scemantic Versioning <https://semver.org/>`__ quite rigorously!
 That means that if you're submitting a breaking change, it will probably take a while before it gets considered.
 
-In that case, you can point your PR to the ``2.0.0-dev`` branch, where the API is being properly developed.
-Otherwise, just point it to ``master``.

 Development Environment
 -----------------------
 
-You can use `flit` to install the package as a symlink:
+This project uses ``flit`` to configure development environments. You can install it using:
 
-.. code-block::
+.. code-block:: sh
 
+    $ pip install flit
+
+And now you can install ``fbchat`` as a symlink:
+
+.. code-block:: sh
+
+    $ git clone https://github.com/carpedm20/fbchat.git
+    $ cd fbchat
     $ # *nix:
     $ flit install --symlink
     $ # Windows:
     $ flit install --pth-file
 
+This will also install required development tools like ``black``, ``pytest`` and ``sphinx``.
+
 After that, you can ``import`` the module as normal.
 
-Before committing, you should run ``black .`` in the main directory, to format your code.

-Testing Environment
--------------------
+Once you're done with your work, please follow the steps below:
 
-The tests use `pytest <https://docs.pytest.org/>`__, and to work they need two Facebook accounts, and a group thread between these.
-To set these up, you should export the following environment variables:
-
-``client1_email``, ``client1_password``, ``client2_email``, ``client2_password`` and ``group_id``
-
-If you're not able to do this, consider simply running ``pytest -m offline``.
-
-And if you're adding new functionality, if possible, make sure to create a new test for it.
+- Run `black .` to format your code.
+- Run `pytest` to test your code.
+- Run `make -C docs html` to verify that the docs still work.
+- Run `make -C docs spelling` to check your spelling in docstrings.
+- Create a pull request, and point it to ``master`` `here <https://github.com/carpedm20/fbchat/pulls/new>`__.
