+
+.PARAMETER SpecsRepoFork
+    The Rest Spec repo fork which contains the config file
+
+.PARAMETER SpecsRepoBranch
+    The Branch which contains the config file
+
+.PARAMETER SpecsRepoName
+    The name of the repo that contains the config file (Can only be either of azure-rest-api-specs or azure-rest-api-specs-pr)
+
+.PARAMETER SdkFolder
+    The path where to generate the code
+
+.EXAMPLE
+    A sample command that uses the function or script, optionally followed
+    by sample output and a description. Repeat this keyword for each example.
+
+.NOTES
