Use 3rd party adminLTE themes with shinydashboard?

Read shinydashboard docs at and wondering if there's an approach currently to apply 3rd-party adminLTE templates, for example

If not is there a walk-through to customize shinydashboard appearance (fonts, colors) or is the only approach to apply a custom .CSS file?

Thx, --Mel.

I haven't done it myself, but it looks like this post might have some helpful tips
