Font Awesome Icon not working in .NET/MVC Application

Kind of simple as the title says but I'm struggling with the steps. I downloaded font-awesome from Nuget Package Manager and added it to my project.

I also added the the font-awesome css in my bundle config file:

bundles.Add(new StyleBundle("~/Content/css").Include(
                      "~/Content/bootstrap.css",
                      "~/Content/site.css",
                      "~/Content/font-awesome.min.css"));

Content/CSS is loaded on my main layout page, which all subsequent pages inherit from.

<meta charset="utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>@ViewBag.Title - My ASP.NET Application</title>
    @Styles.Render("~/Content/css")
    @Scripts.Render("~/bundles/modernizr")

But trying to use the icons in a button form:

<a href="@Url.Action("Edit", "Story", new { id = Model.Id })" class="btn btn-primary">
                    <i class="fas fa-adjust"></i>
                    Edit Story
</a>

Results in nothing showing up. What am I missing in the steps?
