There is no manual on the mysecureshell website. Is there a manual in english anywhere?

my requirements are fairly simple. I have one sftp user that I need to limit to a directory and it's subdirectories to upload and download files.

I've already gone into the etc/passwd file and changed his shell to point to mysecureshell.

now I just need to configure mysecure shell and don;t have access to a gui so I have to fo it manually.

any manual anywhere to explain what I need to do?
