# Helm Charts

Preview will deploy each chart under the `charts` directory, by templating it with a values file under `.preview/chart-values/<chart>.yaml`.

{% hint style="info" %}
Many of these locations can be customized. See the Configuration section.
{% endhint %}

A basic version of the command Preview will use to deploy these charts is:

```
helm upgrade \
	--install \
	--force \
	--atomic \
	--set image.repository=<repository> \
	--set image.tag=<revision> \
	-f ./preview/chart-values/<name>.yaml \
	<name> ./charts/<name>
```
