+# CMake Template
+
+This is an example project using CMake.
+
+The requirements are:
+
+- CMake 3.11 or better; 3.14+ highly recommended.
+- A C++17 compatible compiler
+- The Boost libararies (header only part is fine)
+- Git
+- Doxygen (optional)
+
+To configure:
+
+```bash
+cmake -S . -B build
+```
+
+Add `-GNinja` if you have Ninja.
+
+To build:
+
+```bash
+cmake --build build
+```
+
+To test (`--target` can be written as `-t` in CMake 3.15+):
+
+```bash
+cmake --build build --target test
+```
+
+To build docs (requires Doxygen, output in `build/docs/html`):
+
+```bash
+cmake --build build --target docs
+```
+
+To use an IDE, such as Xcode:
+
+```bash
+cmake -S . -B xbuild -GXcode
+cmake --open xbuild
+```
+
+The CMakeLists show off several useful design patterns for CMake.
