The manual is 87 pages with 35 screenshots embedded in it, which makes it a large file to serve over the web and a fast one to open from your own disk. It installs alongside CofferShield, so it is available offline, in the place you will actually want it — next to the vault.
It covers the anatomy of every screen, all fifteen built-in asset fields, the twelve kinds of debt, all thirty-six insurance fields, the five kinds of password record, and the custom fields and custom layouts subsystem in full — including what happens to your data when you hide a field, narrow its scope, or delete it.
