- Add more concrete instruction for configuring backend
- Explain what users should look for when changing `dev-test/index.html`
- Add more info to use local storage to set Netlify site's URL
The command `yarn start` is dependent on the `npm-run-all` package, therefore we can't recommend this as the first command someone runs after they just clone the repository in case they don't have it globally installed. Trying to `yarn start` without this package gets:
```
/bin/sh: run-s: command not found
error Command failed with exit code 127.
info Visit https://yarnpkg.com/en/docs/cli/run for documentation about this command.
```
Therefore, on first setup it is recommended to run `yarn bootstrap` as the first command.
Inspired by Docker and Yarn. We can add more things later if we need
them, but I think this is a good start.
