+## Releasing a new version
+
+This project follows [semver](http://semver.org/). So if you are making a bug
+fix, only increment the patch level "2.0.x". If any new files are added, a minor
+version "2.x.x" bump is in order.
+
+### Make a release commit
+
+To prepare the release commit, edit the
+[lib/execjs/version.rb](https://github.com/sstephenson/execjs/blob/master/lib/execjs/version.rb)
+`VERSION` value. Then make a single commit with the description as
+"ExecJS 2.x.x". Finally, tag the commit with `v2.x.x`.
+
+```
+$ git pull
+$ vim ./lib/execjs/version.rb
+$ git add ./lib/execjs/version.rb
+$ git ci -m "ExecJS 2.x.x"
+$ git tag v2.x.x
+$ git push
+$ git push --tags
+```
