How to build .NET Core based App for ARM architecture

We currently own a .NET Core based App. We would like to make it work on ARM platform as well. Is there some documentation which can help understand how to go about achieving that?
I searched up on MSFT docs and found a few pages but it is not clear to me all the steps needed to achieve the above based on those docs. Any help is appreciated. I would like to know ways to compile cross platform, using IDEs like Visual Studio/Rider, code/metadata modifications required to project (.csproj) files and anywhere else to achieve this?
