+### Logging
+By default Valve only logs error messages. To also enable warning and information messages,
+set the environment variable `RUST_LOG` to the minimum logging level desired for ontodev_valve:
+`debug`, `info`, `warn`, or `error`.
+For instance:
+```rust
+export RUST_LOG="ontodev_valve=info"
