+`cmkr` can bootstrap itself from CMake and you only need CMake to use it.
 
 ## 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:
+To get started run the following commands from your project directory:
+
+```sh
+curl https://raw.githubusercontent.com/build-cpp/cmkr/main/cmake/cmkr.cmake -o cmkr.cmake
+cmake -P cmkr.cmake
+```
+
+After the bootstrapping process finishes, modify [`cmake.toml`](https://build-cpp.github.io/cmkr/cmake-toml) and open the project in your favorite IDE or build with CMake:
 
 ```sh
 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).
+Once bootstrapped, `cmkr` does not introduce extra steps to your workflow. After modifying `cmake.toml` you simply build/configure your CMake project and `cmkr` will automatically regenerate `CMakeLists.txt`.
+
+In CI settings the `cmkr` bootstrapping process is skipped so there is no extra configure-time overhead in your pipelines.
