a) Unzip the compressed database file if it has a ".zip" extension. Simply double-click the zip file to uncompress (unzip) it. The resulting file should be called "Personal.sohodb". Rename the file to this name if necessary.
b) Open the folder where your database will go. This folder is located at the following path in your Home directory (where ~ denotes your Home directory): ~/Library/Application Support/Chronos/Databases
c) There might already be a "Personal.sohodb" file in this directory. If there is drag it to the Trash or move it to a backup folder on your hard disk.
d) Move the "Personal.sohodb" file from step (a) to the folder in step (b). Your database is now in place and ready for use.
