 #### Not FreeSewing code
+
 This component family only contains re-exports of code by other maintainers.\
 Since they are a dependency, we provide them as part of the <code>@freesewing/react</code> package for convenience.
 
 Please refer to the documentation for [react-diff-viewer-continued][dv] and [jsdiff][jsd].
