+## Label your PRs
+
+This repository uses the release-drafter action to draft and create our change log.
+
+Please add one of the following labels to your PR to specify the type of contribution
+and help categorize the PR in our change log:
+
+- `breaking` -- The PR creates a breaking change to the API.
+- `bug` -- The PR fixes a problem with the code.
+- `feature` or `enhancement` -- The PR introduces a backward-compatible feature.
+- `documentation` or `examples` -- The PR is an addition or update to documentation.
+- `build`, `dependencies`, `chore`, or `ci` -- The PR is related to maintaining the
+  repository or the project.
+
+By default, an unlabeled PR is listed at the top of the change log and is not
+grouped under a heading like *Features* that groups similar PRs.
+Labeling the PRs so we can categorize them is preferred.
+
+If, for some reason, you do not believe your PR should be included in the change
+log, you can add the `skip-changelog` label.
+This label excludes the PR from the change log.
+
+For more information, see `.github/release-drafter.yml` in the repository
+or go to <https://github.com/release-drafter/release-drafter>.
