+You must manually download install the undodb package.
+
+UndoDB is only supported on linux platforms. It will not work on macOS or Windows.
+
+1. Download the tarball from Google Drive.
+
+       https://drive.google.com/open?id=18dx1hHRrPgc27TtvvCe9rLXSYx_rKjzq
+
+   You must be logged into your MongoDB/10gen google account to access this link.
+   This file has MongoDB's private undodb key-server parameters baked into it,
+   so do not share this file outside of the company.
+
+2. Untar and install:
+
+        tar xzf undodb-*.tgz
+        cd undodb-*
+        sudo make install
+
+There is good README help in the undodb directory if you have questions.
+There is also extensive documentation at https://docs.undo.io. 
+
+Please also refer to William Schultz's intro talk for a getting started primer:
