+
+## About Visual Signatures
+
+This tool adds a **visual signature** to your PDF: your name rendered in a handwriting-style font, placed where you want it.
+
+**This is valid for most everyday documents:**
+- Rental agreements and leases
+- School forms and permission slips
+- Basic contracts and agreements
+- Internal approvals and acknowledgments
+
+This is the same type of signature used by DocuSign, HelloSign, and most e-signature tools.
+
+**When you might need more:**
+If you're signing high-stakes legal contracts, government documents, or working in regulated industries (banking, healthcare), you may need a cryptographic digital signature. Consult your legal counsel or compliance team for guidance.
+
 - No installs.
-- No dependencies.
-- Just open `index.html` and sign your PDF.
+- No runtime dependencies. Just open `index.html` and sign your PDF.
