Subtheme of AMP Theme for Drupal 8.
This theme is not production ready.
This is an AMP version of the BYU theme. Due to the nature of AMP, it is no where near as flexible as the normal BYU Drupal 8 theme. You should not and cannot use this as a replacement of that theme.
This theme requires much of the editing to be done in the code, not in theme settings. It does not use web components (AMP does not allow custom compoents).
