+## Starting a new card from boilerplate-card with [devcontainer][devcontainer]
+
+1. Fork and clone the repository.
+2. Open the [devcontainer][devcontainer] and run `npm start` when it's ready.
+3. The compiled `.js` file will be accessible on
+   `http://127.0.0.1:5000/custom-header.js`.
+4. On a running Home Assistant installation add this to your Lovelace
+   `resources:`
+
+```yaml
+- url: "http://127.0.0.1:5000/custom-header.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 `dc start`.
+2. Home Assistant will install and will eventually be running on port `9123`
