 ## 🌟 Why Invio?

 - Built for doing, not configuring — create an invoice, send a link, get paid. No CRMs, projects, or bloat getting in your way.
 - You really own it — self‑hosted by default. Your data lives where you put it, and exporting is always an option.
 - Fast & dependable — Deno + Fresh on the frontend and Hono + SQLite on the backend keep things simple and quick.
 - Client‑friendly — share a secure public link—no accounts or passwords required to view invoices.

 ### Demo mode

 Environment variables:
 
 - `DEMO_MODE=true` — enable demo mode
-- `DEMO_DB_PATH` — path to the pristine demo database file (e.g. `/app/data/invio-demo.db`)
-- `DATABASE_PATH` — active database file that the app writes to (e.g. `/app/data/invio.db`)
+- `DEMO_DB_PATH` — path to the pristine demo database file (e.g.
+  `/app/data/invio-demo.db`)
+- `DATABASE_PATH` — active database file that the app writes to (e.g.
+  `/app/data/invio.db`)
 - `DEMO_RESET_HOURS` — interval in hours between resets (default: `3`)
-- `DEMO_RESET_ON_START` — whether to perform a reset on startup (default: `true`)
+- `DEMO_RESET_ON_START` — whether to perform a reset on startup (default:
+  `true`)
 
 On each reset, the server briefly closes the DB connection, copies the pristine
 demo DB over the active DB, and reinitializes migrations and built-in templates.
