    .. code-block:: bash

    Where the following would be replaced accordingly:
-   
+
    - ``MAJOR.MINOR.PATCH`` is the current version of the pyrf24 package
    - ``cp3X`` is the version of python used to build the wheel (ie ``cp39`` for CPython 3.9)
      The second occurrence of ``cp3X`` describes the CPython ABI compatibility.
    - ``ARCH`` is the architecture type of the CPU. This corresponds to the compiler used.
      On Raspberry Pi OS (32 bit), this will be ``armv7l``.
 
+Differences in API
+~~~~~~~~~~~~~~~~~~
+
+This package intentionally adheres to `PEP8 <https://pep8.org/>`_ standards as much as possible.
+This means that class members' names use snake casing  (eg. ``get_dynamic_payload_size()``)
+instead of using the C++ conventional camel casing (eg. ``getDynamicPayloadSize()``). However,
+the older python wrappers provided with each C++ library (RF24, RF24Network, & RF24Mesh) had used
+camel casing. So, the API provided by this package exposes both snake cased and camel cased
+versions of the API. The camel cased API is not documented to avoid duplicate and
+complicated documentation.
+
+.. code-block:: py
+
+    radio.print_details()  # documented
+    # can also be invoked as
+    radio.printDetails()  # not documented
+
+Some of the C++ functions that do not accept arguments are wrapped as a class property. But, the C++
+style functions are still exposed. For example:
+
+.. code-block:: py
+
+    radio.listen = False
+    # is equivalent to
+    radio.stopListening()  # not documented
+
+    radio.listen = True
+    # is equivalent to
+    radio.startListening()  # not documented
+
+Python Type Hints
+-----------------
+
+This package is designed to only function on Linux devices. But, it is possible to install this
+package on non-Linux devices to get the stub files which help auto-completion and type checking
+in various development environments.

 Documentation

 Before submitting contributions, you should make sure that any documentation changes builds
-successfully. This can be done locally.

-Documentation Dependencies
---------------------------
+successfully. This can be done locally but **on Linux only**. The documentation of API requires
+this package (& all its latest changes) be installed.
 
 This package's documentation is built with the python package Sphinx and the sphinx-immaterial theme.
 It also uses the dot tool provided by the graphviz software to generate graphs.
 
-Install Graphviz
-****************
-
-On Windows, installing Graphviz library is done differently. Check out the
-`Graphviz downloads page <https://graphviz.org/download/>`_. Be sure that the ``graphviz/bin``
-directory is in the ``PATH`` environment variable (there's an option in the installer for this).
-After Graphviz is installed, reboot the PC so the updated ``PATH`` environment variable takes affect.
+1. Install Graphviz
 
-On Linux, just run:
+   .. code-block:: shell
 
-.. code-block:: shell
+       sudo apt-get install graphviz
 
-    sudo apt-get install graphviz
+2. Installing Sphinx necessities
 
-Installing Sphinx necessities
-*****************************
+   .. note::
+       If you installed sphinx using ``apt``, then it is likely out-of-date and will override any virtual
+       python environments installation of Sphinx. Simply uninstall sphinx (using ``apt``) will remedy
+       this problem.
