 # cmkr
 
-cmkr, pronounced "cmaker", is A CMakeLists.txt generator from TOML.
+cmkr, pronounced "cmaker", is a modern build system based on CMake and TOML. It was originally created by [Mohammed Alyousef](https://github.com/MoAlyousef).
 
+**NOTE**: The documentation is currently a work-in-progress due to breaking changes since `0.1.4`. For examples you can check the [cmkr GitHub topic](https://github.com/topics/cmkr) and the [tests](https://github.com/build-cpp/cmkr/tree/main/tests).
 
-## Building
-cmkr requires a C++11 compiler, cmake >= 3.15.

-git clone https://github.com/moalyousef/cmkr
-cd cmkr
