+### pytest live log feature
+
+Pytest Live Log feature duplicates emitted log messages in order to style log statements according to their levels, for this to work use `POWERTOOLS_LOG_DEDUPLICATION_DISABLED` env var.
+
+```bash:title=pytest_live_log.sh
+POWERTOOLS_LOG_DEDUPLICATION_DISABLED="1" pytest -o log_cli=1
+```
+
+<Note type="warning">
+  This feature should be used with care, as it explicitly disables our ability to filter propagated messages to the root logger (if configured).
+</Note><br/>
