@@ -66,8 +66,14 @@ Tactix provides a Symfony Console command `tactix:report` that creates a static
 bin/console tactix:report <folder>
 # or, when installed as a dependency with optional output directory
 vendor/bin/console tactix:report <folder> --out-dir=<out-dir>
+# Exclude specific namespaces from the report (can be used multiple times)
+vendor/bin/console tactix:report <folder> --exclude-namespace="App\\CLI\\" --exclude-namespace="App\\Infrastructure\\"
 ```
 
+Options:
+- `--out-dir`: Base output directory for reports (defaults to project root)
+- `--exclude-namespace`: Namespace prefix to exclude from the report (can be used multiple times). By default, `Doctrine\\`, `Symfony\\`, and `Psr\\` namespaces are excluded. When you provide your own exclusions, you replace these defaults.
+
 Notes:
 - the output files index.html, report.js, chart.js, styles.css are created
 - the command prints discovered classes and forbidden relations and finishes with `Report written to: ./report/index.html`.
