+## Feature Deprecation Policy
+
+As changes are made to Docker there may be times when existing features
+will need to be removed or replace with newer features. Before an existing
+feature is removed it will be labeled as "deprecated" within the documentation
+and will remain in Docker for, usually, at least 2 releases. After that time
+it may be removed.
+
+Users are expected to take note of the list of deprecated features each
+release and plan their migration away from those features, and (if applicable)
+towards the replacement features as soon as possible.
+
+The complete list of deprecated features can be found on the
+[Deprecated Features page](deprecated).
