+## Microbenchmark
+
+Here are instructions on running and tuning the `microbenchmark-pages` target.
+
+```bash
+# On Windows
+% cmake src -B build
+% cmake --build build --config Release
+% .\build\Release\microbenchmark-pages.exe
+
+# On other platforms
+% cmake src -B build -DCMAKE_BUILD_TYPE=Release
+% cmake --build build
+% .\build\microbenchmark-pages.exe
+
+# TODO: Maybe these can be merged into one, just needs testing.
+```
+
+Settings can be set using CMake at configuration time (the first step).
+
+```bash
+% cmake src -B build -DMBP_OBJECT_SIZE=32 -DMBP_OBJECT_DISTANCE=4096
+```
