+HowTo dump flows
+----------------
+
+This section demonstrates how to dump flows. Currently, it's possible to dump
+all flows with assistence of external tools.
+
+#. 2 ways to get flow raw file:
+
+   - Using testpmd CLI:
+
+   .. code-block:: console
+
+       testpmd> flow dump <port> <output_file>
+
+   - call rte_flow_dev_dump api:
+
+   .. code-block:: console
+
+       rte_flow_dev_dump(port, file, NULL);
+
+#. Dump humanreadable flows from raw file:
+
+   Get flow parsing tool from: https://github.com/Mellanox/mlx_steering_dump
+
+   .. code-block:: console
+
+       mlx_steering_dump.py -f <output_file>
