+#### S3-compatible endpoints
+
+The `s3` backend targets Amazon S3 by default. Set `endpoint` to point that same backend at another S3-compatible object store, for example Backblaze B2, Cloudflare R2, or MinIO. Some endpoints also require `force-path-style: true`; MinIO deployments can alternatively use the dedicated [`type: minio`](#minio--s3-compatible) backend.
