+SHOTGUN_API_ALLOW_OLD_PYTHON
+============================
+
+When set to ``1``, ``shotgun_api3``  will allow being imported from Python versions that are no longer supported.
+Otherwise, when unset (or set to any other value), importing the module will raise an exception.
+
+This is not recommended and should only be used for testing purposes.
+
+.. important::
+    The ability to import the module does not guarantee that the module will work properly on the unsupported Python
+    version. In fact, it is very likely that it will not work properly.
