 ## Conclusion
 
-You now have an understanding of SMB (and CIFS), what an SMB share is, and what a mount point is. These pieces of information allow you to share remote data in a way that’s transparent to users. From the user's perspective, the resource is local to the server that they’re accessing. This guide also shows you how to use the mount and umount commands in a basic way to create and delete shares, how to create and use a credentials file to automate the sharing process to some extent, and how to automatically remount the share after a reboot.
