 These are project templates which are used in .NET Core for creating ASP.NET Core applications.
 
 ## Building Templates
-- Run `build.cmd -Pack` in the repository root to build all of the dependencies.
-- Run `build.cmd` in this directory will produce NuGet packages for each class of template in the artifacts directory. These can be installed via `dotnet new -i {nugetpackage path}`
-- The ASP.NET localhost development certificate must also be installed and trusted or else you'll get a test error "Certificate error: Navigation blocked".
-- You also need to get the packages these templates depend on into your package cache or else `dotnet new` restore will fail. The easiest way to get them to run is by letting the build run at least 1 test. Note currently some packages are missed. https://github.com/aspnet/AspNetCore/issues/7388

+1. Run `. .\activate.ps1` if you haven't already.
+
+2. Run `build.cmd -all -pack` in the repository root to build all of the dependencies.
+3. Run `build.cmd` in this directory will produce NuGet packages for each class of template in the artifacts directory.
+4. Because the templates build against the version of `Microsoft.AspNetCore.App` that was built during step 2 it is NOT advised that you install templates created on your local machine via `dotnet new -i [nupkgPath]`. Instead, use the `Run-[Template]-Locally.ps1` scripts in the script folder. These scripts do `dotnet new -i` with your packages, but also apply a series of fixes and tweeks to the created template which keep the fact that you don't have a production `Microsoft.AspNetCore.App` from interfering.
+5. The ASP.NET localhost development certificate must also be installed and trusted or else you'll get a test error "Certificate error: Navigation blocked".
