 Try to keep the volume size low. For example,
 ```bash
- weed master -volumeSizeLimitMB=1024
+weed master -volumeSizeLimitMB=1024

 In addition, you can also configure the per bucket storage this way in `weed shell`:
 ```bash
- fs.configure -locationPrefix=/buckets/ -volumeGrowthCount=1 -apply
+fs.configure -locationPrefix=/buckets/ -volumeGrowthCount=1 -apply
 ```
 This will add 1 physical volume when existing volumes are full. If using replication, you will need to add more volumes, so that it is a multiple of the number of replicas:
 ```bash
- fs.configure -locationPrefix=/buckets/ -replication=001 -volumeGrowthCount=2 -apply
+fs.configure -locationPrefix=/buckets/ -replication=001 -volumeGrowthCount=2 -apply

 # S3 Authentication
+
 By default, the access key and secret key to access `weed s3` is not authenticated. To enable credential based access, you can choose static or dynamic configuration:
 * **Dynamic Configuration**: setup auth with `s3.configure` in `weed shell`
 * **Static Configuration**: create a config.json file similar to the example below, and specify it via `weed s3 -config=config.json`
 
 ## Dynamic Configuration

+Example command:
+```bash
+s3.configure -access_key=any -secret_key=any -buckets=bucket1 -user=me -actions=Read,Write,List,Tagging,Admin -apply

-> s3.configure -access_key=any -secret_key=any -buckets=bucket1 -user=me -actions=Read,Write,List,Tagging,Admin -apply
