How do you add resources to a module generated with New-SampleModule?

I'm developing a module to provide some DSC resources, and then I discovered sampler. Since it's a good idea to do the same things as the community around something, I've been trying to adapt/port my module into one compatible with sampler, but I'm running into some confusion.

I created a module using this command:

```powershell
New-SampleModule -DestinationPath . -ModuleType newDscCommunity -ModuleName MyModule
```
# MOF resources
I'd like to add a resource so I ran this command:

```powershell
> Add-Sample -Sample cAzResourceGroup
____ _ _
| _ \| | __ _ ___| |_ ___ _ __
| |_) | |/ _` / __| __/ _ \ '__|
| __/| | (_| \__ \ || __/ |
|_| |_|\__,_|___/\__\___|_|

Name of your Resource (MyResource): MyResource2
Name of your module (MyModule): MyModule2
What is your source folder? (source):

```

It seems to be adding the DSC_Folder resource no matter what details I give it but I'm not sure whether I'm doing this right.

# Class resources
I tried with a class based resource:

```
Add-Sample -Sample ClassResource -ResourceName cAzResourceGroup
```

This did add something but didn't update `DscResourcesToExport` in the containing module .psd1. The initial tests also failed:

```

```
What's the extra thing I need to do to make it work?

# Importing existing MOF resources

I also have some existing (MOF) resources I'd like to add, but I'm not sure how to hook them into the build. Just copying them into the DSCResources folder didn't seem to do it.

Could someone point me in the right direction to add new resources, and add our existing resources into the module as well?
