 Starting from version 1.7.0, you can also use S3-compatible providers by configuring the endpoint:
 
 ```bash
 # For path-style requests (bucket in the path)
-_APP_STORAGE_S3_ENDPOINT=[PROVIDER_ENDPOINT] # e.g., s3.amazonaws.com (without https://)
-_APP_STORAGE_S3_BUCKET=[BUCKET_NAME] # bucket name required here
+_APP_STORAGE_S3_ENDPOINT=<PROVIDER_ENDPOINT> # e.g., s3.amazonaws.com (without https://)
+_APP_STORAGE_S3_BUCKET=<BUCKET_NAME> # bucket name required here
 
 # OR for virtual-hosted-style paths (bucket in the endpoint)
-_APP_STORAGE_S3_ENDPOINT=[BUCKET_NAME].[PROVIDER_ENDPOINT] # e.g., bucket-name.s3.amazonaws.com
+_APP_STORAGE_S3_ENDPOINT=<BUCKET_NAME>.<PROVIDER_ENDPOINT> # e.g., bucket-name.s3.amazonaws.com
 _APP_STORAGE_S3_BUCKET= # leave this empty when bucket is in the endpoint
 ```
