+# How to Contribute
+
+We want your help to make the Webstore Component Library great. There are a few guidelines that we need contributors to follow so that
+we can have a chance of keeping on top of things.
+
+## Contribution Tasks
+
+* Reviewing and Merging Changes
+
+### Reviewing and Merging Changes
+
+1. Approval Required - Github enforces at least one person approve a pull request.
+2. Required Labels - an appropriate [semver](https://semver.org/) label (see [release.yml](https://github.com/samvera/hyku/blob/main/.github/release.yml))
+
+If one or more of the required checks failed (or are incomplete), the code should not be merged (and the UI will not allow it). If all of the checks have passed, then anyone on the project (preferably the pull request submitter) may merge the code.
