 ## Configuration file
-Slide supports loading configuration from a JSON formatted file called `slide.options.json`. This file can be specified by the `-c` command line option, we will also attempt to read `~/.config/slide/slide.options.json` and `/etc/slide/slide.options.json` in that order. The first file to load is used and its options will override command line parameters.

 ### Immich configuration (lightweight + low power)
 
-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.
+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).

 Immich settings:
 * `url`: base Immich server URL (the integration appends `/api` automatically if missing).
 * `apiKey`: Immich API key (needs `asset.view`, and `asset.download` if `size` is `original`).
+* `userId`: optional user id to retrieve all assets owned by that user via the assets endpoint.
 * `albumId` or `albumIds`: optional album filters.
 * `personId` or `personIds`: optional person filters.
+* `extensions` / `allowedExtensions`: optional list of file extensions to include (for example `["jpg","jpeg","png"]`).
 * `size`: `"fullsize"`, `"preview"`, `"thumbnail"`, or `"original"` (original uses the download endpoint).
 * `order`: `"asc"` or `"desc"` ordering for asset search.
 * `pageSize`: assets fetched per page.
 * `maxAssets`: cap on total assets fetched (0 means no cap).
+* `refreshSeconds`: refresh interval for reloading Immich assets (0 disables).
 * `cachePath`: local cache directory for downloaded images.
 * `cacheMaxMB`: maximum cache size in MB (0 disables cleanup).
 * `includeArchived`: include archived assets in search results.
+If you omit `albumId`/`albumIds`/`personIds`, Immich returns all assets visible to the API key’s user.
+If `userId` is set, album/person filters are ignored and all assets for that user are fetched.
 When `immich` is set on an entry, `path` and `imageList` are ignored.
