Documentation for starting out is great but not much for how to add IOS

Is there any place I could go or someone can tell me how to advance. I have Appium tests and am using a Windows machine the tests are in Visual Studio I also have appium on that machine. I use a physical Android and would like to now incorporate the use of a Mac mini what do I need to do to run the tests from the Windows machine to the Mac mini?

Steps:
1 make your tests start in command line. Example: use Maven with Java
2 install Brew on mac
3 install nodeJS
4 install Java JDK (many still using 8. I am with 11now)
5 install xCode
6 install command line Appium using ‘npm install -g appium’ command
7 build WDA app for real device or simulator or both (depends what you need)

Ready

Thank you. That is very helpful! If its not too much trouble anything you know of for C# command line usage?
