# Page 36 - Getting help for the dotnet tool
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!
