+iOS version compatibility
+-------------------------
+
+The minimum supported iOS version is specified at compile time, using the
+:option:`--host` option to ``configure``. By default, when compiled for iOS,
+Python will be compiled with a minimum supported iOS version of 13.0. To use a
+different miniumum iOS version, provide the version number as part of the
+:option:`!--host` argument - for example,
+``--host=arm64-apple-ios15.4-simulator`` would compile an ARM64 simulator build
+with a deployment target of 15.4.
