 # General Contributing Guidelines
 
-The Material Components contributing policies and procedures can be found in the
-main Material Components documentation repository’s
-[contributing page](https://github.com/material-components/material-components/blob/develop/CONTRIBUTING.md).
-
-For larger feature requests we might ask you to write a
-[Design Doc](https://docs.google.com/document/d/1ISW8sVEQpAs1X-pQ0zf2q3Sbz5NRS8jfjs-jnjo9iWk/edit).

-## Pull Request Process
-
-Because the material-components-android code is stored in two locations (i.e.,

-that is synced into the repository. Even though the PR list shows no merged PRs,
-we do accept contributions.
