How to add synopsis / resume for C # cmdlet?

Question

Suppose you write PSCmdLet in C #:

/// <summary>
/// Get a Qaru exception.
/// </summary>
[Cmdlet(VerbsCommon.Join, "StackOverflow")]
[OutputType(typeof(OverflowException))]
public class JoinStackOverflow : PSCmdlet {
  protected override void ProcessRecord() {
    throw new OverflowException("stack");
  }
}

If the module defining the above is loaded into PowerShell, the command help Join-StackOverflowwill return the following:

NAME
  Join-StackOverflow

SYNTAX
  Join-StackOverflow  [<CommonParameters>]

ALIASES
  None

REMARKS
  None

How can I add a resume / resume for this cmdlet, for example. same as for Get-Process:

NAME
  Get-Process

SYNOPSIS
  Gets the processes that are running on the local computer or a remote computer.

...
