Documents folder is missing from dock

MacBook Pro (Retina 13")  OSX 10.11.6

My documents folder is not on my dock, which it was 20 minutes ago.  Looking at other information, I found all the files in All My Files, under favorites - Documents - all the folders are listed, but how do I get the Documents folder back on my dock?


Thank you.

I finally found it by looking under "Searching this Mac," under "Devices," "My MacBook Pro," found the most recent "Documents" folder listed, and drug it back to the dock.  Thank Heavens.  Just wish I knew what I did to cause this so I don't do it again.
