+Step 1 is about opening a web browser to show the documentation help about a command. It follows this syntax:
+```
+dotnet help <command>
+```
+I gave the example of `dotnet help new`, and although this worked in .NET Core 3 up to .NET 6, with .NET 7 it gives an error! 
+
+Other examples, like `dotnet help run`, work correctly by opening a web browser to show the `run` command's documentation. 
+
+The other type of help, as described in Step 2, is command-line documenation and it follows this syntax:
+```
+dotnet <command> -?|-h|--help
+```
+For example, `dotnet new -?` or `dotnet new -h` or `dotnet new --help` outputs documentation about the `new` command at the command-line.
+
+And so `dotnet help help` opens a web browser for the `help` command, and `dotnet help -h` outputs documentation for the `help` command at the command-line!
