Updating the Bootstrap file

Now before checking the results in the browser, there are a few updates that we need to do. First, open the app.modules.ts file inside the src/app folder and notice the import lines. The red color for the imported class means it does not exist:

        import {About} from './about/about'; 

That is right, because we removed all previous definitions in the seed project, so remove all troubled lines. That includes the following imports:

        import {About} from './about/about'; 
        import {Home} from './home/home'; 
        import {RepoBrowser} from './github/repo-browser/repo-browser'; 
        import {RepoList} from './github/repo-list/repo-list'; 
        import {RepoDetail} from './github/repo-detail/repo-detail'; 

Tip

Please notice that we don't need to mention...
