 ## Logging
 
-SQLmem uses [loguru](https://github.com/Delgan/loguru). Set `SQLMEM_DEBUG=true` for verbose output (every query, cache hit/miss, backup events). Default level is INFO.
+SQLmem is silent by default. Call `add_sink()` to opt in:
+
+```python
+import sys
+from sqlmem import add_sink
+
+add_sink(sys.stderr)                      # INFO by default
+add_sink(sys.stderr, level="DEBUG")       # verbose: every query, cache hit/miss, backup
+add_sink("sqlmem.log", rotation="10 MB") # to a file
+```
+
+Set `SQLMEM_DEBUG=true` in `.env` to make the default level DEBUG when no explicit `level` is passed to `add_sink()`.
