+# Github Actions
+
+This folder contains the definition of a Github action used to build and push the image into a registry and also to setup a minikube cluster to test the deployment of the helm chart.
+
+## setup
+In order to use Github Actions for your repository it's necessary to setup two secrets and two environment variables in your project settings.
+
+1. In Github go into your repository then click `Settings`
+2. On left side you can see a section called `Security`
+3. Click on `Secrets and variables` -> `Actions`
+4. Add the secret `REGISTRY_ROBOT_PASSWORD` (the password used to access to the image registry)
+5. Add the secret `REGISTRY_ROBOT_USERNAME` (the username used to access to the image registry)
+6. Add the variable `REGISTRY_ADDRESS` (the address of the image registry, could be quay.io or docker.io)
+7. Add the variable `REGISTRY_USERNAME` (the username used in the image registry)
+
+Once these variables have been setted it is possible to run the action and see the output
+
+**NOTE**: the action build and push the image with the default tag `latest`
