+Linux Installation
+==================
+
+Applications that use raw Ethernet device discovery, such as PCAP-backed
+discovery, need permission to open raw network sockets. Instead of running your
+application with ``sudo``, grant the installed executable the required Linux
+capabilities:
+
+.. code-block:: bash
+
+   sudo setcap cap_net_raw,cap_net_admin=eip /usr/bin/your-app
+
+Replace ``/usr/bin/your-app`` with the full path to the application executable.
