+Releases
+********
+
+We release a new minor version (e.g., 0.5.0) every few months and bugfix releases if needed.
+The minor versions contain new features, API changes, deprecations, removals, potential backward-incompatible
+changes and also all previous bugfixes included in any bugfix release. With every release, we publish a changelog
+where we list additions, removals, changed functionality and fixes.
+
+Project Management and Decision Making
+**************************************
+
+The decision what goes into a release is governed by the :ref:`staff contributors and leaders <governance>` of
+Lightning development. Whenever possible, discussion happens publicly on GitHub and includes the whole community.
+When a consensus is reached, staff and core contributors assign milestones and labels to the issue and/or pull request and start tracking the development. It is possible that priorities change over time.
+
+Commits to the project are exclusively to be added by pull requests on GitHub and anyone in the community is welcome to review them.
+However, reviews submitted by
+`code owners <https://github.com/PyTorchLightning/metrics/blob/master/.github/CODEOWNERS>`_
+have higher weight and it is necessary to get the approval of code owners before a pull request can be merged.
+Additional requirements may apply case by case.
+
+API Evolution
+*************
+
+Torchmetrics development is driven by research and best practices in a rapidly developing field of AI and machine
+learning. Change is inevitable and when it happens, the Torchmetric team is committed to minimizing user friction and
+maximizing ease of transition from one version to the next. We take backward compatibility and reproducibility very
+seriously.
+
+For API removal, renaming or other forms of backward-incompatible changes, the procedure is:
+
+#. A deprecation process is initiated at version X, producing warning messages at runtime and in the documentation.
+#. Calls to the deprecated API remain unchanged in their function during the deprecation phase.
+#. One minor versions in the future at version X+1 the breaking change takes effect.
+
+The "X+1" rule is a recommendation and not a strict requirement. Longer deprecation cycles may apply for some cases.
