+
+## Features
+
+- Bucket operations:
+- `PUT /{bucket}`
+- `HEAD /{bucket}`
+- `DELETE /{bucket}`
+- `GET /` (list buckets)
+- Object operations:
+- `PUT /{bucket}/{key}`
+- `GET /{bucket}/{key}`
+- `HEAD /{bucket}/{key}`
+- `DELETE /{bucket}/{key}`
+- `GET /{bucket}?list-type=2&prefix=...` (ListObjectsV2-style)
+- Multipart upload:
+- `POST /{bucket}/{key}?uploads` (initiate)
+- `PUT /{bucket}/{key}?uploadId=...&partNumber=N` (upload part)
+- `GET /{bucket}/{key}?uploadId=...` (list parts)
+- `POST /{bucket}/{key}?uploadId=...` (complete)
+- `DELETE /{bucket}/{key}?uploadId=...` (abort)
+- Multi-object delete:
+- `POST /{bucket}?delete` with S3-style XML body
+- AWS SigV4 streaming payload decoding for uploads (`aws-chunked` request bodies)
+
+## Limitations
+
+- No authentication/authorization yet.
+- Not full S3 API coverage.
+- No garbage collection of unreferenced blob chunks yet.
+- No versioning or lifecycle policies.
+- Error and edge-case behavior is still being refined for client compatibility.
