+This project uses CMake, and thus should be easy to integrate
+into any existing project using CMake.
+
+The following commands can be run from the root of this depot,
+and places all build artifacts into `./build`:
+
+```bash
+# Configure cmake for the current environment
+# -S: explicitly specify the source directory
+# -B: explicitly specify the directory for build artifacts
+cmake -S . -B build
+
+# Optionally (recommended) do a clean build each time
+cmake --build ./build --parallel --target clean
+
+# build everything
+cmake --build ./build --parallel --target all
