+## Fixtures
+
+This AST spec comes with a collection of _fixtures_, or small code snippets, used to verify AST correctness.
+
+For more information, see [feat(ast-spec): add fixture test framework and some initial fixtures](https://github.com/typescript-eslint/typescript-eslint/pull/3258).
+
+## Legacy Fixtures
+
+The `legacy-fixtures` folder contains all of the old fixtures from our previous testing framework.
+No new fixtures should be added to this folder, and instead we should be attempting to migrate and remove cases wherever possible.
+
+For more information, see:
+

-## Fixtures
-
-This AST spec comes with a collection of _fixtures_, or small code snippets, used to verify AST correctness.
-
-For more information, see [feat(ast-spec): add fixture test framework and some initial fixtures](https://github.com/typescript-eslint/typescript-eslint/pull/3258).
-
-## Legacy Fixtures
-
-The `legacy-fixtures` folder contains all of the old fixtures from our previous testing framework.
-No new fixtures should be added to this folder, and instead we should be attempting to migrate and remove cases wherever possible.
-
-For more information, see:
