+## What repeatability guarantees does Catch2 provide?
+
+There are two places where it is meaningful to talk about Catch2's
+repeatability guarantees without taking into account user-provided
+code. First one is in the test case shuffling, and the second one is
+the output from random generators.
+
+Test case shuffling is repeatable across different platforms since v2.12.0,
+and it is also generally repeatable across versions, but we might break
+it from time to time. E.g. we broke repeatability with previous versions
+in v2.13.4 so that test cases with similar names are shuffled better.
+
+Random generators currently rely on platform's stdlib, specifically
+the distributions from `<random>`. We thus provide no extra guarantee
+above what your platform does. **Important: `<random>`'s distributions
+are not specified to be repeatable across different platforms.**
