## C++ Quick Start
${SAFARI_WARNING}
#### Installing the Rerun viewer
The Rerun C++ SDK works by connecting to an awaiting Rerun Viewer over TCP.
If you need to install the viewer, follow the [installation guide](https://www.rerun.io/docs/getting-started/installing-viewer). Two of the more common ways to install the Rerun are:
* Via cargo: `cargo install rerun-cli`
* Via pip: `pip install rerun-sdk`
After you have installed it, you should be able to type `rerun` in your terminal to start the viewer.
#### Using the Rerun C++ SDK with CMake
```cmake
include(FetchContent)
FetchContent_Declare(rerun_sdk URL
https://github.com/rerun-io/rerun/releases/latest/download/rerun_cpp_sdk.zip)
FetchContent_MakeAvailable(rerun_sdk)
```
This will download a bundle with pre-built Rerun C static libraries for most desktop platforms,
all Rerun C++ sources and headers, as well as CMake build instructions for them.
By default this will in turn download & build [Apache Arrow](https://arrow.apache.org/)'s C++ library which is required to build the Rerun C++.
See [Install arrow-cpp](https://www.rerun.io/docs/howto/arrow-cpp-install) to learn more about this step and how to use an existing install.
Make sure you link with `rerun_sdk`:
```cmake
target_link_libraries(your_executable PRIVATE rerun_sdk)
```
##### Logging your own data
Put the following code to your `main.cpp`:
```cpp
${EXAMPLE_CODE}
```
Start the rerun viewer (`rerun`) and then build and run your C++ program.
