-* EACH ENTRY SHOULD BE ACCOMPANIED BY EITHER A PUBLIC ISSUE OR A PR (PREFER ISSUES OVER PRS).
-* REREAD ALL ENTRIES FROM THE USERS PERSPECTIVE. WILL IT MAKE SENSE?

+How to use this template
+------------------------
+
+1. Copy the contents into the desired location.
+2. If you're creating the GitHub release, remove the ## [Version]
+3. Add entries to the various sections ensuring you summarise the change; big changes generally
+   require more explanation.
+4. Append an issue or PR to each entry (prefer issues).
+5. If a section doesn't contain any entries, remove the section.
+6. Re-read all changes from the users perspective. Ensure the summary is written so that almost
+   anyone with a foundational knowledge of EKS Anywhere can appreciate what the change means.
+7. If all sections are empty, you shouldn't be creating a release.
+
+When gathering feedback and applying suggestions:
+
+* Re-read the suggest edits in the same fashion as (6).
+* Double check for duplication, punctuation and grammar (ask for help as needed).
+
+General tips
+------------
+
+* Avoid acronyms unless they're accepted industry wide. CRD is domain specific, use Custom
+  Resource Definition instead. I/O is known industry wide as Input/Output so is fine.
+* Use plain language - avoid jargon.
+* Keep sentences concise but clear.
