 SCP server
 ==========
 
-Restricted SSH server which allows SCP / SFTP / RSYNC access only. This image is meant to provide an ability to update content in data containers. You would normally make a constellation of your service, a data container, and the scp-server container.
+Restricted SSH server which allows SFTP access only. This image is meant to provide an ability to update content in data containers. You would normally make a constellation of your service, a data container, and the scp-server container.
 
 The scp-server container is configured at runtime with environment variables to match the configuration of the main service. The environment variables are:
 
-* AUTHORIZED_KEYS - contains the public SSH keys for the users who will be allowed to upload.
-* DATADIR - The location where relative paths start from.
-* USERID - The numeric id of the `data` account. Defaults to 33.
-* GROUPID - The numeric id of the `data` group. Defaults to 33.
+**Environment Variables:**
+* `AUTHORIZED_KEYS` - contains the public SSH keys for the users who will be allowed to upload.
+* `USERID` - The numeric id of the `data` account. Defaults to 33.
+* `GROUPID` - The numeric id of the `data` group. Defaults to 33.
 
-Original code and idea is from https://github.com/gituser173/docker-scp-server.
+**Volumes:**
+* `/home/data` - Directory where all your data is
+* `/etc/ssh/host_keys` - Generated `HostKeys` go here. Mount a volume here so they don't get regenerated all the time the container boots.
