+Python versions
+===============
+
+The PyAnsys ecosystem follows `SPEC-0`_ for Python version support,
+which is also similar to `NEP 29`_. This means:
+
+* PyAnsys packages are expected to drop support for Python versions **3 years** after their
+  initial release.
+
+You can find below the timeline for the end of support for each Python version according to the SPEC-0 policy
+as well as a table showing the Python versions supported by each PyAnsys metapackage, which might slightly
+differ from the SPEC-0 policy but is always aligned with it.
+
+* Grayed out Python versions are no longer supported by the current version of the PyAnsys metapackage.
+* Light blue Python versions are currently supported.
+* Dark blue Python versions are upcoming Python releases for which support is expected in the future.
