+`cmkr`, pronounced "cmaker", is a modern build system based on [CMake](https://cmake.org/) and [TOML](https://toml.io). 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).

 ```toml

 ```
 
-## Building
+`cmkr` can bootstrap itself from CMake and consumers of your project do not need to install anything to work with it.
 
-`cmkr` requires a C++11 compiler and CMake >= ~3.x (exact minimum version is not yet specified). C++11 was picked to allow the broadest possible set of compilers to bootstrap `cmkr`.
+## Getting started
+
+The easiest way to get started is to use the [cmkr_for_beginners](https://github.com/build-cpp/cmkr_for_beginners) template repository. Either open it in [Gitpod](https://gitpod.io/#https://github.com/build-cpp/cmkr_for_beginners), or clone the repository and run:
 
 ```sh
-git clone https://github.com/moalyousef/cmkr
-cd cmkr
-cmake -Bbin
-cmake --build bin --parallel
+cmake -B build
+cmake --build build
 ```
 
+Alternatively you can check out the [cmkr topic](https://github.com/topics/cmkr), the [build-cpp organization](https://github.com/build-cpp) or the [tests](https://github.com/build-cpp/cmkr/tree/main/tests) for more examples and templates. You can also check out the [documentation](https://build-cpp.github.io/cmkr).
+
 ## Command line

+## Getting started
+
+The easiest way to get started is to use the [cmkr_for_beginners](https://github.com/build-cpp/cmkr_for_beginners) template repository. Either open it in [Gitpod](https://gitpod.io/#https://github.com/build-cpp/cmkr_for_beginners), or clone the repository and run:
+
+```sh
+cmake -B build
+cmake --build build
+```
+
+Alternatively you can check out the [cmkr topic](https://github.com/topics/cmkr) or the [build-cpp organization](https://github.com/build-cpp) for more examples and templates.

+
+`cmkr`, pronounced "cmaker", is a modern build system based on [CMake](https://cmake.org/) and [TOML](https://toml.io). It was originally created by [Mohammed Alyousef](https://github.com/MoAlyousef).
+
+`cmkr` parses `cmake.toml` files and generates a modern, idiomatic `CMakeLists.txt` for you. A minimal example:
+
+```toml
+[project]
+name = "cmkr_for_beginners"
+description = "A minimal cmkr project."
+
+[target.hello_world]
+type = "executable"
+sources = ["src/main.cpp"]
+```
+
+`cmkr` can bootstrap itself from CMake and consumers of your project do not need to install anything to work with it.
