+the `RCLONE_BWLIMIT` environment variable:
 
 ```console
 export RCLONE_BWLIMIT=1M
 ```
 
+As rustic allows to set environment variables in the config profile, you can
+alternatively use:
+
+```toml
+[global.env]
+RCLONE_BWLIMIT = "1M"
+```

 For debugging rclone, you can set the environment variable `RCLONE_VERBOSE=2`.

+| Huawei Cloud OBS              | `obs`      |
+| Microsoft OneDrive            | `onedrive` |
+| Aliyun Object Storage Service | `oss`      |
+| Amazon S3                     | `s3`       |
+| WebDAV                        | `webdav`   |
+| WebHDFS                       | `webhdfs`  |
+
+## Configuration
+
+The configuration for the services is done via the `rustic` configuration file.
+
+For example, to configure the `Amazon S3` service, you would add the following
+to the configuration file:
+
+```toml
+[repository]
+repository = "opendal:s3"
+password = "password"
+
+# Other options can be given here - note that opendal also support reading config from env
+# files or AWS config dirs, see the opendal S3 docs for more information
+# https://opendal.apache.org/docs/rust/opendal/services/struct.S3.html
+[repository.options]
+access_key_id = "xxx" # this can be ommited, when AWS config is used
+secret_access_key = "xxx" # this can be ommited, when AWS config is used
+bucket = "bucket_name"
+root = "/path/to/repo"
+```
+
+`opendal` is used to access the services. The `s3` postfix is used to specify
+the `Amazon S3` service. For other services, the postfix is replaced with the
+respective service postfix.
+
+You can find more service templates in the
+[rustic repository](https://github.com/rustic-rs/rustic/tree/main/config).
+
+To see the service-dependent options to be set in `[repository.options]`, please
+refer to the
+[opendal service documentation](https://opendal.apache.org/docs/rust/opendal/services/).
