+## S3 configuration
+
+To enable an s3 endpoint for your filer with a default install add the following to your values.yaml:
+
+```yaml
+filer:
+  s3:
+    enabled: true
+```
+
+### Enabling Authenticaion to S3
+
+To enable authentication for S3, you have two options:
+
+- let the helm chart create an admin user as well as a read only user
+- provide your own s3 config.json file via an existing Kubernetes Secret
+
+#### Use the default credentials for S3
+
+Example parameters for your values.yaml:
+
+```yaml
+filer:
+  s3:
+    enabled: true
+    enableAuth: true
+```
+
+#### Provide your own credentials for S3
+
+Example parameters for your values.yaml:
+
+```yaml
+filer:
+  s3:
+    enabled: true
+    enableAuth: true
+    existingConfigSecret: my-s3-secret
+```
+
+Example existing secret with your s3 config to create an admin user and readonly user, both with credentials:
+
+```yaml
