+CircleCI will take care of publishing the updated packages to npm from there.
+
+If for some reason CircleCI fails to publish the npm package, you may do so
+manually by running `npm publish` from the package directory. Make sure to
+include the `--tag canary` parameter if you are publishing a canary release!
