Could not find the module 'cChocoInstaller' when I try to compile my DSC configuration

Question

I'm trying to get Chocolatey installed to manage packages on a a windows VM using Powershell DSC.

I've prepared my configuration file

Configuration chocandfirefox {
    Import-DscResource -ModuleName cChoco
    Import-DscResource -ModuleName cChocoInstaller
    Import-DscResource -ModuleName cChocoPackageInstaller
       
    Node 'localhost' {

        cChocoInstaller installChoco
        {
            InstallDir = "c:\ProgramData\chocolatey"
        }

         cChocoPackageInstaller installGit
        {
             Name = "firefox"
            DependsOn = "[cChocoInstaller]installChoco"
        }

    }
}

But when I try to compile it to a .mof, I'm told

> +     Import-DscResource -ModuleName cChocoInstaller
> +     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Could not find the module 'cChocoInstaller'. At
> C:\Users\auser\Documents\PowerShell\DSC\Configuration_chocandfirefox.ps1:4

>     + CategoryInfo          : ParserError: (:) [], ParseException
>     + FullyQualifiedErrorId : ModuleNotFoundDuringParse

I'm sure I'm missing something fundamental but I've worked through docs on DSC and Chocolatey and can't spot it.

You should only need to import cChoco.

Looking at one of the examples provided in the GitHub repository, we can see:

Configuration InstallChoco
{
    Import-DscResource -Module cChoco
    Node "localhost"
    {
        cChocoInstaller InstallChoco
        {
            InstallDir = "c:\choco"
        }
        # ...
    }
}

They're using cChocoInstaller after only importing cChoco. cChocoInstaller is a resource within the module cChoco.
