+## 3. Project Structure
 
+In order to separate template logic from code this project was divided into 2 parts:
+ - This repository: documentation for using the template, scripts for the template, documentation of the whole project
+ - [core]: code base the whole project
 
+This separation enables users to more easily update the code after applying the template because using a template repository creates an entire separate Git history.
