-* Start the demo and Install all the dependencies (*Note. do it this way only the first time, and be aware, it will take some time*)
+Start using published components
+---
+
+This is recommended if you are running from the `master` branch.
+
+Start the demo-shell app after installing all the dependencies from npm (*Note. do it this way only the first time, and be aware, it will take some time*)
 
 ```sh
 ./start.sh -install
 ```

+Or, if you have previously run `-install` but want to update the dependencies, use `-update`
+
+```sh
+./start.sh -update
+```
+
+If there are no big changes in the demo-shell since you last started then you can start without `-install` and `-update` to skip fetching packages, which should be much quicker
 
 ```sh
 ./start.sh
 ```
 
-* Start the demo, install all the dependencies, and remove the previous version of the npm packages (*Note. do this only after big changes*):

+
+This will remove previous versions of all packages, before running `npm install` again
 
 ```sh
 ./start.sh -cleanInstall
 ```

+This is recommended if you are using the `development` branch or a feature branch off `development`
 
 * If you want to use your local components use the following script with any of the previous option. It will npm link all the components
 in the demo shell:
