Simple Template Renderer is just that: a very simple tool that can take a file or directory, perform some key-value-pair find/replace on file names and file text, and write the result to a specified location.
To get started with using this library as a dotnet tool, check out the NuGet page.
Check out the MSDN docs on global vs. local dotnet tools and set up your environment accordingly.
Once installed, call simple-template-renderer --help to see the options that are available.
