# Module are used to register the components. with Modules you can achieve lazy loading. Can you share the exact error which you are getting. Running a complete code not feasible. You can directly use the About us component provided that it is register under App module. Then no need to use of about-us Module.
# i removed the module. there is no specific error, it's just when every time I click the about us button the page flickers but it stays on the home page
