+# Real-Time HAT
+
+The Real-Time HAT extends the Gigabit-Ethernet interface of the Raspberry Pi by professional networking functions.
+Typical applications are **industrial real-time communication** and **network monitoring**.
+
+The HAT provides **3 Gigabit-Ethernet ports**, one of which connecting to the Raspberry Pi's Ethernet port.
+Connection to the Raspberry Pi is realized via the GPIO connector and via a (short) Ethernet cable. Interface SPI0 is for main configuration, using either CE0# or CE1#. 
+Additional information on use cases, programming interfaces etc. can be found on [InnoRoute's website](https://innoroute.com/realtimehat/)., e.g., on using the HAT as an **endpoint in Time-Sensitive Networks**, as a **3-port Ethernet switch**, or to **measure and monitor** any kind of the traffic forwarded through the HAT.
+
+To install the necessary software, use the following commands:
+
+```bash
+git clone https://github.com/InnoRoute/RealtimeHAT
+cd RealtimeHAT
+./install.sh
+```
