+Commands:
+* `play` / `resume` — resume slideshow
+* `pause` — pause slideshow
+* `next` / `next-image` — advance to next image
+* `next-folder` — jump to next configured path (if multiple paths are configured)
+* `restart` / `reset` — recreate the selector and restart playback
+If `immichTopic` is not set, it defaults to `<topic>/immich`.
+
+Immich control topic (`immichTopic`):
+* `album:<id>` or `albumIds:id1,id2` — filter to one or more album IDs
+* `person:<id>` or `personIds:id1,id2` — filter to one or more person IDs
+* `user:<id>` / `userId:<id>` / `ownerId:<id>` — show all assets owned by a user (clears album/person filters)
+* `extensions:jpg,jpeg,png` — filter by file extension (useful for RAW exclusion)
+* `reset` / `clear` — clear album/person/user filters
+* JSON payloads are also accepted, for example:
+```
+{"albumIds":["..."],"personIds":["..."],"order":"desc","size":"fullsize","userId":"...","extensions":["jpg","jpeg"]}
+```

 ### Immich configuration (lightweight + low power)

-Immich uses an API key and a `/api` base path. This integration requests the asset search endpoint and downloads thumbnail images into a local cache before displaying them. That keeps bandwidth and power usage low while still letting `slide` do its normal scaling and transitions.
+Immich uses an API key and a `/api` base path. This integration requests the asset search endpoint and downloads the configured image size into a local cache before displaying them. That keeps bandwidth and power usage low while still letting `slide` do its normal scaling and transitions. If you have RAW/HEIC images, set `size` to `preview`/`thumbnail` or use `extensions` to limit results to JPEG/PNG; `slide` will also fall back to `preview` if a `fullsize` download isn't readable.
+
+#### Getting an Immich API key
+
+In the Immich web UI, go to Settings and find **API Keys** (menu labels can vary by version), then create a new key and copy it.
+
+#### Required API key permissions
+
+`slide` uses Immich search plus the asset view/download endpoints, so the API key should include:
+* `asset.read` — required by Immich search endpoints (used to retrieve asset metadata).
+* `asset.view` — required for the viewAsset endpoint (thumbnail/preview/fullsize).
+* `asset.download` — required if you set `size` to `original` (download endpoint).
