-## Known issues
+## About the 404 page (specific to github pages only)
 
 The old `github-pages:deploy` command created a `404.html` in the `dist` folder.
-This was required to fully support the router [`PathLocationStrategy`](https://angular.io/docs/ts/latest/api/common/index/PathLocationStrategy-class.html). Right now you have to copy `index.html` to `404.html` on your own. Please submit an [issue](https://github.com/angular-buch/angular-cli-ghpages/issues) if you want this feature back.
