+## Generator: Resource ID
+
+Each Service Definition contains one or more Resource ID's - this tool allows the generation of:
+
+* Resource ID Formatters
+* Resource ID Parsers
+* Resource ID Structs
+
+This is run via go:generate whenever the provider is compiled - at this time this doesn't wipe an existing "parse" folder so it's possible to mix and match if necessary.
+
+## Example Usage
+
+```
+go run main.go -path=-path=./ -name=MyResourceType -id=/subscriptions/12345678-1234-9876-4563-123456789012/resourceGroups/resGroup1/providers/Microsoft.AnalysisServices/servers/Server1
+```
+
+## Arguments
+
+* `help` - Show help?
+
+* `id` - An example of the Azure Resource ID for this Resource.
+
+* `name` - The name of this Resource Type, without the Service Name. For example `AnalysisServicesServer` becomes `Server`.
+
+* `path` - The Relative Path to the Service Package.
