+# Release Notes
+
+This directory is used to store release notes for each version.
+
+The release notes for each version are stored in a subdirectory named after the release tag, following the format `vX.Y.Z`.
+
+Each release directory will contain the following two files:
+
+* `GITHUB_RELEASE.md`: The release notes formatted for GitHub Releases.
+* `RELEASE_NOTES.adoc`: The release notes in AsciiDoc format.
+
+For example, the release notes for version 1.2.3 would be structured as follows:
+
+```text
+release-notes/
+└── v1.2.3/
+    ├── GITHUB_RELEASE.md
+    └── RELEASE_NOTES.adoc
+```
