(Visual D) it is not clear on how to install dub packages into project.

[Shadowblitz16]

Hello, its not very clear how to install dub packages into 
existing visual D projects.
I tried using the packages manager to run "dub add dsfml" however 
that froze the package manager and I had to go into task manager 
and force end the dub process.

there really needs to be a clear explanation on this as dub is 
the official package manager for the d language and I have still 
yet to figure out how to use it.

this is not just for visual D but other IDE implementations of 
the d language.
when I go to the dub website it simply says... "to install run 
"dub add <packagename>""
however when trying this it says I must first run "dub init" 
which i'm not sure is per project or once per computer.

anyhow this system is clearly flawed for beginners.
something as simple as "dub add <packagename>" would be fine.
especially if it auto generated a project based on folder name 
and login details if one didn't exist.

what I am wondering is how do I install packages with visual D in 
visual studio 2019?
I currently have had better luck with c++ due to video tutorials 
and that's pretty bad since you have to link c++ files, which in 
itself is a pain in the ass and definitely not beginner friendly.
