 ## Required Secrets
 
 The *seqr* application expects a few secrets to be defined for the services to start.

You should create these secrets in your kubernetes cluster prior to attempting to install the chart.

 Alternatively, you can use your preferred method for defining secrets in kubernetes. For example, you might use [External Secrets](https://external-secrets.io/) to synchronize secrets from your cloud provider into your kubernetes cluster.
