Keep a site's paperwork in one place
Most sites come with paperwork — a building permit, a structural drawing, a warranty certificate, a signed contract. Site Documents lets you attach those files directly to the site they belong to, so anyone who opens the site can find them in seconds instead of hunting through email or a shared drive.
Site Documents is a project feature. To turn it on, open Project Settings → Sites → Advanced Settings and turn on Enable Site Documents. Each site then gets a Site Documents page in its settings, and a Documents tab on its dashboard once files are attached.
