 use the secret key as `xxxxxx/xxxx`  it will work fine.

+### Minio ###
+
+[Minio](https://minio.io/) is an object storage server built for cloud application developers and devops.
+
+It is very easy to install and provides an S3 compatible server which can be used by rclone.
+
+To use it, install Minio following the instructions from the web site.
+
+When it configures itself Minio will print something like this
+
+```
+AccessKey: WLGDGYAQYIGI833EV05A  SecretKey: BYvgJM101sHngl2uzjXS/OBF/aMxAN06JrJ3qJlF Region: us-east-1
+
+Minio Object Storage:
+     http://127.0.0.1:9000
+     http://10.0.0.3:9000
+
+Minio Browser:
+     http://127.0.0.1:9000
+     http://10.0.0.3:9000
+```
+
+These details need to go into `rclone config` like this.  Note that it
+is important to put the region in as stated above.
+
+```
+env_auth> 1
+access_key_id> WLGDGYAQYIGI833EV05A
+secret_access_key> BYvgJM101sHngl2uzjXS/OBF/aMxAN06JrJ3qJlF   
+region> us-east-1
+endpoint> http://10.0.0.3:9000
+location_constraint> 
+server_side_encryption>
+```
+
+Which makes the config file look like this
+
+```
+[minio]
+env_auth = false
+access_key_id = WLGDGYAQYIGI833EV05A
+secret_access_key = BYvgJM101sHngl2uzjXS/OBF/aMxAN06JrJ3qJlF
+region = us-east-1
+endpoint = http://10.0.0.3:9000
+location_constraint = 
+server_side_encryption = 
+```
+
+Minio doesn't support all the features of S3 yet.  In particular it
+doesn't support MD5 checksums (ETags) or metadata.  This means rclone
+can't check MD5SUMs or store the modified date.  However you can work
+around this with the `--size-only` flag of rclone.
+
+So once set up, for example to copy files into a bucket
+
+    rclone --size-only copy /path/to/files minio:bucket
