+## Experimental checks
+
+Before checks are promoted to stable, they may be available as experimental
+checks. Experimental checks are disabled by default. To see the list of
+experimental checks available, refer to the [Build checks reference](/reference/build-checks/).
+
+To enable all experimental checks, set the `BUILDKIT_DOCKERFILE_CHECK` build
+argument to `experimental=all`:
+
+```console
+$ docker build --check --build-arg "BUILDKIT_DOCKERFILE_CHECK=experimental=all" .
+```
+
+You can also enable experimental checks in your Dockerfile using the `check`
+directive:
+
+```dockerfile {title=Dockerfile}
+# syntax=docker/dockerfile:1
+# check=experimental=all
+```
+
+To selectively enable experimental checks, you can pass a CSV string of the
+check IDs you want to enable, either to the `check` directive in your Dockerfile
+or as a build argument. For example:
+
+```dockerfile {title=Dockerfile}
+# syntax=docker/dockerfile:1
+# check=experimental=JSONArgsRecommended,StageNameCasing
+```
+
+Note that the `experimental` directive takes precedence over the `skip`
+directive, meaning that experimental checks will run regardless of the `skip`
+directive you have set. For example, if you set `skip=all` and enable
+experimental checks, the experimental checks will still run:
+
+```dockerfile {title=Dockerfile}
+# syntax=docker/dockerfile:1
+# check=skip=all;experimental=all
+```
