+How to use FaPro to simulate multiple devices in network
+</h1>
+<br/>
+
+## Introduction
+
+  Network and service simulation can already be done using FaPro. However, in a real environment, there are often multiple different devices in a network, and each device runs different services. To simulate a real network environment, it is necessary to simulate these devices.
+
+  To simulate a device in a network, we need to simulate all open services on that device. We defined device rules, a rule is a set of service information on all open ports of a device.
+
+  With FaPro, you can create a virtual network and simulate several different devices in it with a single command.
+
+  We've created a set of device rules for surveillance video equipment from over 30 manufacturers:

+
+## Usage
+Download [Camera Device Rules Pack](https://github.com/fofapro/fapro/raw/master/rules/camera.pak)
+
+Then run fapro with root user to create the simulated device from the rules pack:
+```shell
+sudo ./fapro run -f camera.pak -v
+```
+A virtual network of 8.0.0.0/8 will be generated, and the device IP will be randomly generated.
