+# Release Guidelines
+
+## Recommended Reading
+
+- https://go.dev/doc/modules/managing-source
+
+## Process
+
+1. Collect the relevant commits:
+
+```
+git log --pretty=format:"%h %s %an <%ae>" -- core/
+```
+
+or
+
+```
+jj log --no-graph -T 'commit_id.short() ++ " " ++ description.first_line() ++ " " ++ author ++ "\n"' core
+```
+
+2. If it's a patch compatible change, only update the patch number. Otherwise,
+   match the version number of the last go-libp2p release.
+
+3. `git tag core/$VERSION` With the following loose template (adjust as needed)
+
+```
+vX.Y.Z – [Release type: Major | Minor | Patch]
+
+Summary:
+- Short sentence describing the purpose of the release (e.g. new feature, bugfixes, breaking changes).
+
+Changes:
+- [Added/Changed/Fixed] <package/type/function>: <short description>
+- [Added/Changed/Fixed] <package/type/function>: <short description>
+- …
+
+Breaking Changes (if any):
+- <Describe removed/renamed types, functions, or changed behavior>
+- <Mention minimum supported Go version if bumped>
+
+Notes:
+- <Optional: migration instructions, links to changelog, docs, or release notes>
+```
+
+4. Publish the tag `git push origin core/$VERSION`
