ASP.NET framework MVC5 empty project NuGet Packages


I’m currently learning MVC5 and I’m stuck with NuGet packages. Actually I want to add some NuGet packages like bootstrap to visual studio 2019 community edition and use it for all projects and solutions but I don’t know how to do this. Every time I create a new project I have to install the package again.
Anyone help me please I want to install the package at once and not again and again.
