How can I include documentation in a geodatabase? I have a database I am going to distribute to other users and would like to be able to include a text document or link to a text document to supply supplemental information and documentation.
You could create the file gdb, then add that to a folder you create (with a .txt readme). However, what you probably want to do is edit the metadata and document your geodatabase design. Here's some information on that:
