 `BW_HOST` can be omitted if you are using the Bitwarden SaaS offering.
 
 After that it is a basic helm deployment:

+## RegistryCredential

+
+```yaml
+---
+apiVersion: "lerentis.uploadfilter24.eu/v1beta3"

+  id: "A Secret ID from bitwarden"
+  name: "Name of the secret to be created"

+The resulting secret looks something like this:

+Expose these to the operator as described in this example:
+
+```yaml

+    value: "https://bitwarden.your.tld.org"
+  - name: BW_CLIENTID

+  - name: BW_CLIENTSECRET
+    value: "YoUrCliEntSecRet"
+  - name: BW_PASSWORD
+    value: "YourSuperSecurePassword"
+```
+
+you can also create a secret manually with these information and reference the existing secret like this in the `values.yaml`:
