+## 1. Getting Started  (Another PR that reflects these changes)
+1. Launch .\tools\PS-VSPrompt shortcut
+	1. This starts VS Dev command prompt in PowerShell
+2. Import module that helps in performing basic repository tasks
+	1. Import-Module Repo-Tasks.psm1
+	2. Type Get-Commands -Module Repo-Tasks to see list of cmdlets
+	3. Get-Help <CommandName> to get help on individual commands.
+
+## 2. Accquring TestFramework
+Current Version: [1.4.0-preview](https://www.nuget.org/packages/Microsoft.Rest.ClientRuntime.Azure.TestFramework/1.4.0-preview)
+
+Nuget command to install current version
+
+    Install-Package Microsoft.Rest.ClientRuntime.Azure.TestFramework -v 1.4.0-preview -Pre
+
+## 3. Setup prior to Record/Playback of tests
+In order to Record/Playback a test, you need to setup a connection string that consists various key/value pairs that provides information to the test environment.
+
+#### 3.1 Environment Variables
+> TEST_CSM_ORGID_AUTHENTICATION
+
+> AZURE_TEST_MODE
+
+    e.g.	
+    TEST_CSM_ORGID_AUTHENTICATION=SubscriptionId=<valid SubscriptionId>;ServicePrincipal=<ClientId>;ServicePrincipalSecret=<Client Secret>;AADTenant=<tenantId>;Environment=Prod;BaseUri=https://management.azure.com/;AADAuthEndpoint=https://login.windows.net/;GraphUri=https://graph.windows.net/
+
+	AZURE_TEST_MODE=Record
+
+#### 3.2.  Supported Keys in connection string
+	* ManagementCertificate
+	* SubscriptionId
+	* AADTenant
+	* UserId
+	* Password
+	* ServicePrincipal
+	* ServicePrincipalSecret
+	* Environment={Prod | DogFood | Next | Current}
+	* RawToken
+	* RawGraphToken
+	* HttpRecorderMode={Record | Playback}
+	* AADTokenAudienceUri
+	* BaseUri
+	* GraphUri
+	* GalleryUri
+	* IbizaProtalUri
+	* DataLakeStoreServiceUri
+	* DataLakeAnalyticsJobAndCatalogServiceUri
+	* AADAuthEndpoint
+	* GraphTokenAudienceUri

+## 4. Record/Playback Test
+#### Playback Test
+1. The default mode is Playback mode, so no setting up of connection string is required.
+
+#### Record Test with Interactive login using OrgId
+	TEST_CSM_ORGID_AUTHENTICATION=SubsctiptionId={SubId};UserId={orgId};AADTenant={tenantId};Environment={env};HttpRecorderMode=Record;
+
+#### Record Test with ServicePrincipal
+	TEST_CSM_ORGID_AUTHENTICATION=SubsctiptionId={SubId};ServicePrincipal={clientId};ServicePrincipalSecret={clientSecret};AADTenant={tenantId};Environment={env};HttpRecorderMode=Record;
+
+2. Run the test and make sure that you got a generated .json file that matches the test name in 	the bin folder under *SessionRecords folder
+3. Copy SessionRecords folder inside the test project and add all *.json files in Visual Studio 	setting "Copy to Output Directory" property to "Copy if newer"
+4. To assure that the records work fine, delete the connection string (default mode is Playback mode) OR change HttpRecorderMode within the connection string to "Playback"
+
+## 5. Change Test Environment settings at run-time
+#### 1. Once you set your connection string, you can add or update key/value settings
+
+	Add new key/value pair
+ 	TestEnvironment.ConnectionString.KeyValuePairs.Add("Foo", "FooValue");
+
+	Update Existing key/value pair
+	TestEnvironment.ConnectionString.KeyValuePairs["keyName"]="new value"
+
+	Accessing/Updating TestEndpoints
+	TestEnvironment.Endpoints.GraphUri = new Uri("https://newGraphUri.windows.net");
+
+###Note:###
+Changing the above properties at run-time has the potential to hard code few things in your tests. Best practice would be to use these properties to change values at run-time from immediate window at run-time and avoid hard-coding certain values.
