# ☸️  Helm Review

## Description

Deploy your [helm](https://helm.sh/docs/intro/quickstart/) charts as a review environment when a pipeline is run in a merge request

## How to use it

1. Prepare your project with the files needed for the [helm chart](https://helm.sh/docs/chart_template_guide/getting_started/)

2. Add the corresponding URL to your `.gitlab-ci.yml` file (see [Getting
