+# Contributing
+
+Thanks for your interest in `chakra-react-select`! All forms of contribution are
+welcome, from issue reports to PRs and documentation / write-ups.
+
+Before you open a PR:
+
+- In development, run `npm run install:all` to setup the dependencies for the
+  core package and the demo.
+- Run `npm run dev` to build (and watch) the package source, as well as run the
+  demo project which can be viewed at http://localhost:5152.
+- Please ensure all the examples work correctly after your change.
+- Also run `npm run lint` to ensure that the change meets the projects code
+  style setup.
+- Make sure there's an issue open for any work you take on and intend to submit
+  as a pull request - it helps core members review your concept and direction
+  early and is a good way to discuss what you're planning to do.
+- If you open an issue and are interested in working on a fix, please let us
+  know. We'll help you get started, rather than inadvertently doubling up on
+  your hard work.
+- All new features and changes need documentation. If you don't have time to
+  write any, leave a note in your PR.
