+Creating modules in Angular helps organize your application into manageable, cohesive units. Each module can encapsulate related components, directives, pipes, and services. Here's a detailed guide on how to create and use modules in Angular.
+
+Creation Methods:
+
+-     Generate Modules: Use ng generate module module-name.
+-     Define Modules: Use @NgModule decorator to declare components, import other modules, and export components.
+-     Create and Add Components: Generate and add components to the module.
+-     Import Modules: Import your new module into app.module.ts or other feature modules.
+-     Feature Modules: Use feature modules for large applications to manage related functionalities.
