 Bitwarden CRD Operator is a kubernetes Operator based on [kopf](https://github.com/nolar/kopf/). The goal is to create kubernetes native secret objects from bitwarden.

 ## Getting started
 
 You will need a `ClientID` and `ClientSecret` ([where to get these](https://bitwarden.com/help/personal-api-key/)) as well as your password.
