Subject: [PATCH] fix: config.json lives in /app/data/ volume, not baked into
 image
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- entrypoint copies example config to /app/data/config.json on first run
- symlinks /app/config.json → /app/data/config.json so app code unchanged
- theme.json also symlinked from /app/data/ if present
- config persists across container rebuilds without extra bind mounts
- updated README with new config/theme instructions

-**Persist your database** across container rebuilds by using a named volume (`meshcore-data`) or bind mount (`-v ./data:/app/data`).
+Config lives in the data volume at `/app/data/config.json` — a default is created on first run. To edit it:
+```bash
+docker exec -it meshcore-analyzer vi /app/data/config.json
+```
+
+Or use a bind mount for the data directory:
+```bash
+docker run -d \
+  --name meshcore-analyzer \
+  -p 3000:3000 \
+  -p 1883:1883 \
+  -v ./data:/app/data \
+  meshcore-analyzer
+# Now edit ./data/config.json directly on the host
+```
+
+**Theme customization:** Drop a `theme.json` in the same data directory (`/app/data/theme.json`) to override default colors, branding, and node/packet type colors for all users. Use the built-in customizer (Tools → Customize) to design your theme and download the file.
