-To then run the app locally, you will have to install javascript `node.js`. A
-good way to do this, is to install [node version manager](https://github.com/nvm-sh/nvm)
-(NVM) to help you deal with different version of `node.js`.

-```
-nvm install node
-nvm install 9
+```shell
+docker run -it --rm -p 8080:8080 -v $(pwd):/src --entrypoint bash \

-
-### Serve the app locally
-``` bash
 npm run serve
