+The compose templates keep full application logs in `./data/logs/app.log` and split warnings/errors into `warn.log` and `error.log`. Keep `MEDIASTATION_LOGGING_LEVEL=info` while diagnosing subscription, site search, organizer, or STRM generation issues; temporarily switch to `debug` only when deeper tracing is needed.
+
+Use a writable container path for STRM output, such as `/data/strm` or a mounted media path. Deployments that previously saved `/app/data/strm` are migrated automatically to the configured `MEDIASTATION_APP_DATA_DIR`, which defaults to `/data`.
