+## Fleet refactoring
+At the moment, IdeaVim is under an active refactoring aiming to split IdeaVim into two modules: vim-engine and IdeaVim.

+If you develop a plugin that depends on IdeaVim: We have an instrument to check that our changes don't affect
+the plugins in the marketplace. Also, we commit to support currently used API at least till the end of 2022.
+If you still encounter any issues with the newer versions of IdeaVim, please [contact maintainers](https://github.com/JetBrains/ideavim#contact-maintainers).
+We kindly ask you not to use anything from the new API (like `VimEditor`, `injector`) because at the moment we don't
+guarantee the compatibility of this API in the future versions.
