-# ExchangeSimulator
+# ExchangeSimulator
+
+A cross-platform exchange matching engine simulator written in modern C++23.
+
+## Building
+
+```bash
+cmake -S . -B build
+cmake --build build
+```
+
+Pass optional flags to enable developer tooling:
+
+```bash
+cmake -S . -B build -DENABLE_ASAN=ON          # AddressSanitizer
+cmake -S . -B build -DENABLE_CLANG_TIDY=ON    # clang-tidy analysis
+```
+
+Requires the [spdlog](https://github.com/gabime/spdlog) library to be available to the build system.
