-## Getting Started
+## Getting started
+
+### Production (Docker)
+
+```bash
+cp .env.example .env
+# Edit .env with your NTFY_URL if desired
+docker compose pull
+docker compose up -d
+```
+
+On first launch, the app detects no account is configured and opens a **setup wizard** in the browser. Fill in three steps — checkwriter info, bank info, and account/routing numbers — then start entering checks.
+
+If you have an existing ezCheckPrinting `.mdb` file, click **Import .mdb** instead.
 
 ### Development (local)
 
 ```bash
 npm install
 cp .env.example .env
-node migrations/import-mdb.js --file /path/to/YourAccount.mdb
-npm run dev
+npm run dev        # nodemon src/app.js
 ```
 
-### Production (Docker)
+## Importing from ezCheckPrinting (.mdb)
+
+Two ways to import:
+
+**Via the UI (recommended):** Click **Import .mdb** in the toolbar, select the file, and click Import. The server runs the migration and shows the log output.
+
+**Via CLI** (inside the container or locally with `mdbtools` installed):
 
 ```bash
-docker compose up -d
+docker exec -it check-printing node migrations/import-mdb.js \
+  --file "/app/data/YourAccount.mdb"
+
+# Preview without writing:
+node migrations/import-mdb.js --file YourAccount.mdb --dry-run
 ```
 
-## Migration
-
-The import script reads a single `.mdb` file and populates the SQLite database.
-It requires `mdbtools` to be installed on the host or available in the container.
-
-```bash
-node migrations/import-mdb.js --file "Montana Dinosaur Center.mdb"
-```
+The script imports account config (T100), logo (Settings), check layout (T200), and check history (T104).
 
 ## Printing
 
-- Select 1–3 checks from the ledger
-- Click "Print PDF"
-- App generates a 3-up 8.5"×11" PDF (three 3.667" check slots)
-- PDF opens in browser, user sends to printer
-- Checks are marked as printed in the ledger
+1. Select 1–3 checks from the ledger (checkbox column)
+2. Click **Generate PDF**
+3. A 3-up 8.5"×11" PDF opens in a new tab — three 3.667" check slots per page
+4. Print from the browser; checks are marked as printed in the ledger
 
-## Check Layout Coordinate Space
+Use the **Reprint** button on printed checks to regenerate without re-marking them.
 
-Coordinates are in inches. Origin is top-left of each check slot.
-Check slot dimensions: 8.5" wide × 3.667" tall (three per letter page).
-MICR line is hardcoded at Y = 3.4" (0.267" from bottom of slot).
+## Check layout
 
-## MICR Font
+- Page: 8.5" × 11", zero margins
+- Three slots of 3.667" each
+- MICR line at Y = 3.4" from top of slot (0.267" from bottom)
+- MICR format: `A{routing}A {account}C {checkNo}A` (GnuMICR E-13B encoding)
 
-Place `micrenc.ttf` or `GnuMICR.ttf` in the `fonts/` directory.
-Update `MICR_FONT_PATH` in `.env` if using a different filename.
+## CI/CD
+
+Push to `main` triggers a GitHub Actions workflow that builds a multi-arch Docker image (amd64/arm64) and pushes it to Docker Hub as `dogiakos/check-printing:latest`. An ntfy notification is sent on success or failure.
+
+## Environment variables
+
+See `.env.example`. Key variables:
+
+| Variable | Default | Description |
+| -------- | ------- | ----------- |
+| `PORT` | `3000` | HTTP port |
+| `DB_PATH` | `data/check-printing.db` | SQLite database path |
+| `MICR_FONT_PATH` | *(see .env.example)* | Path to GnuMICR.otf inside container |
+| `NTFY_URL` | — | ntfy topic URL for push notifications |
