+### Updating npm-shrinkwrap.json
+
+Use **npm v5+** for this.
+General workflow to update `npm-shrinkwrap.json` would be:
+
+- `npm install --no-optional` -  with old npm-shrinkwrap (--no-optional to skip fsevents)
+- update `package.json` if you need to remove/update/add any packages
+- remove `npm-shrinkwrap.json`
+- `npm install --no-optional` with new `package.json`
