I'm new to grails, I can't find a good tutorial to install bootstrap in grails 3+ (3.1.5), and I can't get what the plugin "twitter bootstrap plugin" is exactly for, isn't it enough to replace layouts/main.gsp with a bootstrap template? is It recommanded to use bootstrap with grails or there is a better alternative? Thank you  

**EDIT :**  

The correct answer is the one given by Jeff Scott Brown in comment  

*"If you are using Grails 3, Bootstrap is installed in a newly created app by default. You don't have to install it."*
