+This repository uses standard [Semantic Versioning](https://semver.org), but also
+provides moving tags for each major version for those who want to get the latest Open
+Dylan releases automatically. For example, the "v3" tag always points to the latest
+release with major version 3, e.g., `v3 -> v3.2.1`.  The major version of
+`install-opendylan` only changes when the Action itself is changed incompatibly, as with
+normal SemVer semantics.
