+# Viam C++ SDK Examples
+
+This directory contains some examples for working with the Viam SDK, ranging from component and service examples to module examples which show how to create modular resources.
+
+Note that with the exception of examples in the [`project`](./project) directory, all these examples are _part of the C++ SDK build tree_, which means that their build files only work if you are using them within an existing SDK build. For learning about SDK features and concepts this is fine, but it is **not** what you should use for starter code if you want, for example,  to develop and deploy a standalone C++ module which lives outside of the SDK build tree. For that look in the [`project`](./project) directory, where you will find CMake and Makefile code which adapts the source code from the simple module example to work as a standalone project which consumes the Viam C++ SDK as a dependency.
