I have read your blog on How can you create custom content types in Drupal.It was very interesting and helpful but I can add some extra points in your article. Here some extra points:
1.Open example.theme
2.Add the code snippet below.
3.Replace example in the function name example_theme_suggestions_page_alter with your actual theme name.
4.Refresh the cache.
