+# Changesets
+
+This directory contains changeset files used to track changes for the next release.
+
+## Adding a changeset
+
+When making a user-facing change, run:
+
+```sh
+bunx changeset add
+```
+
+Or manually create a file `.changeset/<slug>.md`:
+
+```md
+---
+"kilo-code": minor
+---
+
+Short description of the change for the changelog.
+```
+
+Use `patch` for bug fixes, `minor` for new features, `major` for breaking changes.
+
+Changeset files are consumed when the version bump PR is merged, updating `CHANGELOG.md` and bumping `package.json` versions.
