+# libicsneo C++ Example
+
+This is an example console application which uses libicsneo to connect to an Intrepid Control Systems hardware device. It has both interactive and simple examples for sending and receiving CAN & CAN FD traffic.
+
+## Building
+
+This example shows how to use the C++ version of libicsneo with CMake. It will build libicsneo along with your project.
+
+First, you need to clone the repository onto your local machine. Run:
+
+```shell
+git clone https://github.com/intrepidcs/libicsneo-examples --recursive
+```
+
+Alternatively, if you cloned without the `--recursive flag`, you must enter the `libicsneo-examples` folder and run the following:
+
+```shell
+git submodule update --recursive --init
+```
+
+If you haven't done this, `third-party/libicsneo` will be empty and you won't be able to build!
+
+### Windows using Visual Studio 2017+
+
+1. Launch Visual Studio and open the `libicsneo-examples` folder.
+2. Choose `File->Open->CMake...`
+3. Navigate to the `libicsneocpp-example` folder and select the `CMakeLists.txt` there.
+4. Visual Studio will process the CMake project.
+5. Choose the dropdown attached to the green play button (labelled "select startup item...") in the toolbar.
+6. Select `libicsneocpp-simple-example.exe`
+7. Press the green play button to compile and run the example.
+
+### Ubuntu 18.04 LTS
+
+1. Install dependencies with `sudo apt update` then `sudo apt install build-essential cmake libusb-1.0-0-dev libpcap0.8-dev`
+2. Change directories to your `libicsneo-examples/libicsneocpp-example` folder and create a build directory by running `mkdir -p build`
+3. Enter the build directory with `cd build`
+4. Run `cmake ..` to generate your Makefile.
+    * Hint! Running `cmake -DCMAKE_BUILD_TYPE=Debug ..` will generate the proper scripts to build debug, and `cmake -DCMAKE_BUILD_TYPE=Release ..` will generate the proper scripts to build with all optimizations on.
+5. Run `make libicsneocpp-interactive-example` to build.
+    * Hint! Speed up your build by using multiple processors! Use `make libicsneocpp-interactive-example -j#` where `#` is the number of cores/threads your system has plus one. For instance, on a standard 8 thread Intel i7, you might use `-j9` for an ~8x speedup.
+6. Now run `sudo ./libicsneocpp-interactive-example` to run the example.
+    * Hint! In order to run without sudo, you will need to set up the udev rules. Copy `libicsneo-examples/third-party/libicsneo/99-intrepidcs.rules` to `/etc/udev/rules.d`, then run `udevadm control --reload-rules && udevadm trigger` afterwards. While the program will still run without setting up these rules, it will fail to open any devices.
+7. If you wish to run the simple example instead, replace any instances of "interactive" with "simple" in steps 5 and 6.
