-## Benchmarks
+## Building
 
-A variety of programs to execute various kinds of tests, 
-including benchmarks, stability and robustness tests.
+Building the benchmark tests must be enabled using:
 
-### Building
+```bash
+cmake -DBUILD_BENCHMARKS=ON ..
+```
 
-Building the benchmark tests must be enabled using 
+Geos uses Google Benchmarks for validating performance of Geos library. It can be built using the following ways:
 
-    cmake -DBUILD_BENCHMARKS=ON ..
+### Linux
+
+Install via package manager:
+
+```bash
+# Debian/Ubuntu
+sudo apt install libbenchmark-dev
+
+# Fedora
+sudo dnf install google-benchmark-devel
+```
+
+Then build:
+
+```bash
+mkdir build && cd build
+cmake -DBUILD_BENCHMARKS=ON ..
+make -j$(nproc)
+```
+
+### Windows (MSYS2)
+
+Install Google Benchmark via pacman:
+
+```bash
+# MINGW64
+pacman -S mingw-w64-x86_64-benchmark
+
+# UCRT64
+pacman -S mingw-w64-ucrt-x86_64-benchmark
+
+# CLANG64
+pacman -S mingw-w64-clang-x86_64-benchmark
+
+# CLANGARM64
+pacman -S mingw-w64-clang-aarch64-benchmark
+```
+
+Then build:
+
+```bash
+mkdir build && cd build
+cmake -G "MinGW Makefiles" -DBUILD_BENCHMARKS=ON ..
+mingw32-make -j$(nproc)
+```
+
+### Windows (MSVC / vcpkg)
+
+```bash
+vcpkg install benchmark:x64-windows
+mkdir build && cd build
+cmake -DBUILD_BENCHMARKS=ON -DCMAKE_TOOLCHAIN_FILE=$VCPKG_ROOT/scripts/buildsystems/vcpkg.cmake ..
+cmake --build . --config Release
