+## Versioning
+
+This library is versioned based on Semantic Versioning ([SemVer](https://semver.org/)).
+
+#### Version scoping
+
+The scope of what is covered by the version number excludes:
+
+- error messages; the text of the messages can change, unless specifically documented.
+
+#### Releasing new versions
+
+- create a release branch
+- update the changelog below
+- update version and copyright-years in `./LICENSE.md` (bottom) and `./src/uuid.lua` (in
+  doc-comments header)
+- create a new rockspec and update the version inside the new rockspec:<br/>
+  `cp uuid-dev-1.rockspec ./rockspecs/uuid-X.Y.Z-1.rockspec`
+- test: run `make test` and `make lint`
+- clean and render the docs: run `make clean` and `make docs`
+- commit the changes as `release X.Y.Z`
+- push the commit, and create a release PR
+- after merging tag the release commit with `X.Y.Z`
+- upload to LuaRocks:<br/>
+  `luarocks upload ./rockspecs/uuid-X.Y.Z-1.rockspec --api-key=ABCDEFGH`
+- test the newly created rock:<br/>
+  `luarocks install uuid`
+
+## Version history
