 ## Options for running EDMarketConnector
 
 ### Run from source
-Until we use any Python feature (such as forthcoming 'matches' in Python 3.10)
-that isn't supported in Python 3.8 versions,
-you can attempt to [run from source](https://github.com/EDCD/EDMarketConnector/wiki/Running-from-source)
-under Python 3.8, but we make no guarantees about this working now, or in
-the future.
-At that point you will either need to fork and apply workarounds, or accept
-that you can no longer run the latest version of ED Market Connector *and are
-stuck with any bugs that affect your use of the application*.
+Due to subsequent changes to the application source it will no longer 
+function with Python 3.8 or 3.9.
 
-Use the latest 3.8 version from [python.org](https://www.python.org/downloads/windows/).
-You need the 32-bit version. **NB: As of Python 3.8.12 they no longer release
-windows installers/packages, so you would have to find a way to compile
-python from source in order to use the latest**.
-This is due to the
-[PEP-0602 policy](https://www.python.org/dev/peps/pep-0602/).
-
-*It really is in your best interests to be using Windows 10*.
-
-
-**WE OFFER ZERO SUPPORT FOR RUNNING ANYTHING BUT THE VERY LATEST VERSION OF
-THIS APPLICATION, ON A SUPPORTED OS, WITH A SUPPORTED PYTHON VERSION.**
-Certainly any bugfixes will only be applied to, at most, the latest release
-Major.Minor version and our current development branch (ready for a future
-Major or Minor increment).
+Do **NOT** attempt to simply run the last version that works under Python 3.8.
+Given application updates and changes since Windows 7 support
+ended you would be running a buggy and generally less useful application.
+For example, most EDDN Listeners will be ignoring any data that doesn't
+state the `gameversion` it comes from.  You need to be running at least
+EDMarketConnector 5.6.0, and really do want to be using the latest version.
