I would like to install an Angular Template on my web hosting, on a sub domain. I found several for free on google, but I have a white page when i try it on the browser.

I am completely beginner on Angular.
Do you know how to activate it?

I don't know anything about angular, but I believe it needs to be compiled. I don't know how to do this as I have no angular experience, but is there a reason you chose an angular template?

This tutorial should help you get started with compiling your angular code into javascript that your browser can interpret.
