 Following parameters are available for `S3` backend.
 
-| Parameter     | Type       | Description                                                                                                                                                                                                                                                                                                                      |
-| ------------- | ---------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
-| `s3.endpoint` | `Required` | For S3, use `s3.amazonaws.com`. If your bucket is in a different location, S3 server (s3.amazonaws.com) will redirect Stash to the correct endpoint. For DigitalOCean, use `nyc3.digitaloceanspaces.com` etc. depending on your bucket region. For S3-compatible other storage services like Minio / Rook use URL of the server. |
-| `s3.bucket`   | `Required` | Name of Bucket. If the bucket does not exist yet it will be created in the default location (`us-east-1` for S3). It is not possible at the moment for Stash to create a new bucket in a different location, so you need to create it using a different program.                                                                 |

+| `s3.insecureTLS` | `Optional` | Specify whether to skip TLS certificate verification. Setting this field to `true` disables verification, which might be necessary in cases where the server uses self-signed certificates or certificates from an untrusted CA. Use this option with caution, as it can expose the client to man-in-the-middle attacks and other security risks. Only use it when absolutely necessary. |
