-## Strict Mode
+## Compilation Constraints and Checks
 
-The Rego compiler supports `strict mode`, where additional constraints and safety checks are enforced during compilation.
-Compiler rules that will be enforced by future versions of OPA, but will be a breaking change once introduced, are incubated in strict mode.
-This creates an opportunity for users to verify that their policies are compatible with the next version of OPA before upgrading.

-Compiler Strict mode is supported by the `check` command, and can be enabled through the `--strict`/`-S` flag.
-
-```
--S, --strict enable compiler strict mode
