+- [ ] For public APIs, new features, etc., a PR on the
+      [docs repo](https://github.com/dgraph-io/dgraph-docs) staged and linked here. This process can
+      be simplified by going to the [public docs site](https://docs.dgraph.io/) and clicking the
+      "Edit this page" button at the bottom of page(s) relevant to your changes. Ensure that you
+      indicate in the PR that this is an **unreleased** feature so that it does not get merged into
+      the main docs prematurely.
 
 **Instructions**
 
-- The PR title should follow the [Conventional Commits](https://www.conventionalcommits.org/)
-  syntax, leading with `fix:`, `feat:`, `chore:`, `ci:`, etc.
+- The PR title should follow the
+  [Conventional Commits](https://www.conventionalcommits.org/en/v1.0.0/#summary) syntax, leading
+  with `fix:`, `feat:`, `chore:`, `ci:`, etc. Ensure any breaking changes are appropriately marked
+  with a `!`. For instance, `feat(dql)!: Remove the foobar func` would indicate that this is a
+  breaking change to the DQL syntax.
 - The description should briefly explain what the PR is about. In the case of a bugfix, describe or
   link to the bug.
