+# App Assets
+
+This directory contains logos and screenshots for the dashboard.
+They are baked into the Docker image at build time.
+
+## Naming convention
+
+Files must follow the felhom.eu website convention:
+
+- `{slug}-logo.svg` — App logo (SVG preferred, displayed on dark background)
+- `{slug}-logo.png` — App logo fallback (PNG, for apps without SVG)
+- `{slug}-screenshot-1.webp` — First screenshot
+- `{slug}-screenshot-2.webp` — Second screenshot (and so on)
+
+The dashboard tries SVG first, falls back to PNG if not found.
+
+Example:
+```
+paperless-ngx-logo.svg
+paperless-ngx-screenshot-1.webp
+adventurelog-logo.png
+adventurelog-screenshot-1.webp
+```
+
+## Syncing from felhom.eu website
+
+Run `make sync-assets` to copy assets from the felhom.eu website repo.
+This expects the website files to be available at `../felhom.eu/website/assets/`
+(relative to this repo), or set `WEBSITE_ASSETS_DIR` to override.
+
+Alternatively, copy files manually from FileBrowser at https://felhom.eu.
