+#### Browser language
+
+Set `BROWSER_LOCALE` to a [BCP-47](https://www.rfc-editor.org/rfc/bcp/bcp47.txt) language tag like `en-US`, `de-DE`, `fr-FR`, `pl-PL`, or `zh-CN` to fix the browser's language and `Accept-Language` header. When unset, Byparr derives the locale from the egress country (e.g. a French proxy → `fr-FR`), keeping the browser language consistent with the exit IP.
+
+Valid tags are maintained in the [IANA Language Subtag Registry](https://www.iana.org/assignments/language-subtag-registry/language-subtag-registry). For a friendlier list, see [List of ISO 639-1 codes](https://en.wikipedia.org/wiki/List_of_ISO_639-1_codes) (language) combined with an [ISO 3166-1 alpha-2](https://en.wikipedia.org/wiki/ISO_3166-1_alpha-2) region code for the full tag, e.g. `pt-BR`.

+### Open WebUI Integration

+Byparr can serve as an external web loader for [Open WebUI](https://github.com/open-webui/open-webui), allowing it to fetch web content through Byparr's anti-bot bypassing capabilities.

+#### Proxmox OCI / LXC browser launch errors
+
+If you are running Byparr as an OCI container in Proxmox (or another LXC-based setup) and see a `FileNotFoundError` from `multiprocessing.synchronize`/`camoufox` when processing requests, increase the service's shared memory in `compose.yaml`:
+
+```yaml
+services:
+  byparr:
+    shm_size: 512mb
+    stdin_open: true
+    tty: true
+```
+
+`shm_size: 512mb` is usually enough; `stdin_open` and `tty` are only needed if your orchestrator runs the container without a TTY.
