+#### Using CMake Preset
+
+[CMake Preset](https://cmake.org/cmake/help/latest/manual/cmake-presets.7.html)
+is a new CMake functionality that provides one-line configure + test.
+
+You can use `gcc-debug` to setup a debug orienated `inplace_vector` development environment.
+
+```text
+$ cmake --workflow --preset gcc-debug
+Executing workflow step 1 of 3: configure preset "gcc-debug"
+
+Preset CMake variables:
+
+  BEMAN_BUILDSYS_SANITIZER="MaxSan"
+  CMAKE_BUILD_TYPE="Debug"
+  CMAKE_CXX_STANDARD="20"
+  CMAKE_TOOLCHAIN_FILE="cmake/gnu-toolchain.cmake"
+
+-- The CXX compiler identification is GNU 14.2.0

+
+Note that this workflow compiles the project with sanitizers,
+if you wish to playaround with `inplace_vector` without sanitizers,
+use `gcc-release`.
