Starting a new card from boilerplate-card with devcontainer

Note: this is available only in vscode ensure you have the Remote Containers extension installed.

1. Fork and clone the repository.
2. Open a devcontainer terminal and run npm start when it's ready.
3. The compiled .js file will be accessible on http://127.0.0.1:5000/boilerplate-card.js.
4. On a running Home Assistant installation add this to your Lovelace resources:

- url: 'http://127.0.0.1:5000/boilerplate-card.js'
  type: module

Change "127.0.0.1" to the IP of your development machine.

Bonus

If you need a fresh test instance you can install a fresh Home Assistant instance inside the devcontainer as well.

1. Run the command container start.
2. Home Assistant will install and will eventually be running on port 9123
