In an effort to save you from some of the trials and tribulations I endured (due to my vast ignorance) I have some basic templates for you to download.  
 
This will give you a basic Exhibit site oriented towards teaching history and with all the data neatly held in a Google spreadsheet.  
 
The Google spreadsheet will make adding and changing data quick and easy.  It will also create the opportunity for multiple authors by allowing others permission to edit the page or you can manually add content from Excel or other spreadsheet programs.
