Hello,

I am following the tutorial of [https://blog.kitware.com/slicercat-creating-custom-applications-based-on-3d-slicer/](https://blog.kitware.com/slicercat-creating-custom-applications-based-on-3d-slicer/) and I have created a directory contains the CMakeLists for my custom slicer build by using the Custom app template generation procedure :

```auto
pip install cookiecutter jinja2-github
cookiecutter gh:KitwareMedical/SlicerCustomAppTemplate

```

Now I have this folder:

My question is what I must do after those steps.  
I tried to follow build instruction for Mac OS:

I don’t know what path source I must use in the cmake command: the path source of Slicer or the path source of the directory of the generated template.

Please I need your help!!

You don’t need to checkout and edit the cookie cutter code. All you need to do is call it: `cookiecutter gh:KitwareMedical/SlicerCustomAppTemplate`

You can make changes anytime and then need to build the application again to make the changes have an effect. You don’t need to rebuild from scratch, so these builds will take just a few minutes and not hours.
