+Additional color classes for Bootstrap 4.  Based on the [Material Design palette](https://material.io/guidelines/style/color.html#color-color-palette).
 
 ## Notes:
 * Link this CSS after you link to Bootstrap.css.
 * Use the included color classes instead of .btn-primary, .alert-danger, etc.
-* Navbars need both the .navbar-inverse (or .navbar-default for lighter colors, try both and see which works for you) and .navbar-[color] classes to appear properly.
-* We recommend using [Bootswatch Paper](http://bootswatch.com/paper/) (a material design Bootstrap theme) with this stylesheet.  We don't test or support it on other themes, actually.
+* Navbars need .navbar-dark or .navbar-light to appear properly, choose according to your colors.
+* We recommend using [Bootswatch Materia](https://bootswatch.com/materia/) (a material design Bootstrap theme) with this stylesheet.
