        region_name="us-west-004",
        bucket_name="your-bucket",
        retries=5,
    ) as s3:
        # Upload & download (overwrite=False by default, skips if file matches)
        await s3.upload_file("local.txt", "remote/path/file.txt")
        await s3.download_file("remote/path/file.txt", "downloaded.txt")
        await s3.download_file("remote/path/file.txt", "downloaded.txt", overwrite=True)  # force re-download

        exists = await s3.object_exists("remote/path/file.txt")
        objects = await s3.list_objects(prefix="remote/path/")

        # Folder operations (overwrite=False by default, skips unchanged files)
        await s3.upload_folder(s3_folder_key="remote/folder/", local_folder_path="local_folder/")
        await s3.download_folder(s3_folder_key="remote/folder/", local_folder_path="local_download/")
        await s3.sync_folder(s3_key="remote/folder/", local_folder_path="local_sync/")

        await s3.verify_file("local.txt", "remote/path/file.txt", use_md5=True)
        await s3.verify_folder_sync(s3_folder_key="remote/folder/", local_folder_path="local_folder/")

        # Quick text/bytes
        await s3.put_text("hello", "remote/hello.txt")
        res = await s3.get_text("remote/hello.txt")
        print(res["text"])
