 # Installing Python
 
-If Python isn't already available on your system,  detailed instructions by platform can be found in the [Python Setup and Usage][using python] section of the official documentation.

+If Python isn't already available on your system, detailed instructions by platform can be found in the [Python Setup and Usage][using python] section of the official documentation.
+Real Python also offers a [nice guide][helpful guide] to installation on various platforms, including iOS and Android.
 
-Exercism tests and tooling currently supports `Python 3.8` (tests) and `Python 3.9` (tooling).
+Finally, these posts by Brett Cannon [A quick-and-dirty guide][quick-and-dirty] and [Why you should use `python -m pip`][python-m-pip], give very helpful advice on how to manage Python installations and packages.
 
+**Note for MacOS users:**  prior to MacOS Monterey (12.3), `Python 2.7` came pre-installed with the operating system.
+Using `Python 2.7` with exercsim or most other programs is not recommended.
+You should instead install Python 3 via one of the methods detailed below.
+As of MacOS Monterey (12.3), no version of Python will be pre-installed via MacOS.

+-  [Windows][windows] Additionally, this Microsoft article on [installing Python on windows][python-on-windows] is helpful.
+-  [Unix & Linux Systems][unix-and-linux] (_these largely work for MacOS as well_)
+-  [MacOS][macos] : **This is outdated.**
+   We recommend reviewing some of the methods outlined in the Real Python article [Installing Python][installing-python] or the articles by Brett Cannon linked above.

+Exercism tests and tooling currently support `Python 3.8` (_tests_) and `Python 3.9` (_tooling_).
+This means that the [newest features of Python `3.10`][310-new-features] are **not** currently supported.
+Please refer to the [Python 3.9.x documentation][3.9 docs] for what is currently supported.
