+# Tally Counter
+
+Run the app with Docker Compose (recommended). The container startup/entrypoint will create the runtime folders and apply migrations; pass numeric PUID/PGID via environment to run as a non-root user.
+
+
+```yaml
+services:
+  tally-counter:
+    image: gitea.kanawave.net/sebastas/tally-counter:latest     #this image
+    container_name: tally-counter
+    restart: unless-stopped
+    networks:
+      - proxy   # connect any proxy networks (for traefik)
+    environment:
+      - PUID=1000   # host uid forwarded to container
+      - PGID=1000   # host gid forwarded to container
+    ports:
+      - "3000:3000" # Set whatever port you want on the left side (host)
+    volumes:
+      - ./tally-counter:/data         # persistent DB + uploads (bind mount)
+```
+
+Add any `labels` for traefik
+
+### Notes & tips
+
+The entrypoint will:
+- ensure `$DATA_DIR` exists,
+- create `sqlite.db` if missing,
+- run `prisma migrate deploy` (if CLI available and migrations exist),
+- then drop privileges to the provided `PUID:PGID` and exec the app.
