+# Lattice SDK C++
+
+[![Version](https://img.shields.io/github/v/release/anduril/lattice-sdk-cpp)](https://github.com/anduril/lattice-sdk-cpp/releases)
+
+The official [Anduril](https://www.anduril.com/) Lattice SDK for C++.
+
+## Documentation
+
+See the documentation for [Lattice C++ SDK](https://docs.anduril.com/sdks/cpp).
+
+## Requirements
+
+⚠️ It's very important that the versions of lib protobuf match the version that it was compiled with as C++ requires very specific [guarantees](https://protobuf.dev/support/cross-version-runtime-guarantee/#cpp). The current requirements are:
+
+* `gRPC == 1.68.0`
+* `Protobuf == 29.0.0`
+* `CMake >= 3.16`
+
+## Installation
+
+The only supported way of install the C++ SDK is by fetching the package using CMake. Please use a fixed version of `GIT_TAG` to ensure that
+you are not impacted by dependency updates of `gRPC` or `Protobuf`. The latest version is available [here](https://github.com/anduril/lattice-sdk-cpp/releases/latest).
+
+### CMakeLists.txt
+
+```cmake
+cmake_minimum_required(VERSION 3.14.0)
+project(lattice-sdk-example)
+
+# Download the SDK from github and add it as part of the project
+include(FetchContent)
+FetchContent_Declare(
+  lattice-sdk-cpp
+  GIT_REPOSITORY https://github.com/anduril/lattice-sdk-cpp.git
+  GIT_TAG v1.0.0
+)
+FetchContent_MakeAvailable(lattice-sdk-cpp)
+
+# Other build instructions
+....
+
+# Link SDK with your sample application.
+target_link_libraries(sample_app lattice-sdk-cpp)
+``` 
+
+## Support
+
+For support with this library please [file an issue](https://github.com/anduril/lattice-sdk-cpp/issues/new) or reach out to your Anduril representative.
