+## Static analysis support
+
+> Introduced in Catch2 X.Y.Z.
+
+Some parts of Catch2, e.g. `SECTION`s, can be hard for static analysis
+tools to reason about. Catch2 can change its internals to help static
+analysis tools reason about the tests.
+
+Catch2 automatically detects some static analysis tools (initial
+implementation checks for clang-tidy and Coverity), but you can override
+its detection (in either direction) via
+
+```
+CATCH_CONFIG_EXPERIMENTAL_STATIC_ANALYSIS_SUPPORT     // force enables static analysis help
+CATCH_CONFIG_NO_EXPERIMENTAL_STATIC_ANALYSIS_SUPPORT  // force disables static analysis help
+```
+
+_As the name suggests, this is currently experimental, and thus we provide
+no backwards compatibility guarantees._
+
+**DO NOT ENABLE THIS FOR BUILDS YOU INTEND TO RUN.** The changed internals
+are not meant to be runnable, only "scannable".
