-## Building and Testing
-
-### Local Development Build
-
-```powershell
-# Build for debugging
-.\build\Build-Debug.ps1
-
-# Run tests
-.\build\Run-Tests.ps1
-```
-
-### Build Requirements
-- .NET 8 SDK installed
-- PowerShell 7.4+ installed
-- For Windows: Visual Studio 2022 or later (optional, for IDE)
-
-### Testing Guidelines
-
-1. **Test Location**: Tests go in `src/Tests/` matching the feature area structure
-2. **Test Naming**: Follow pattern `{Verb}Pnp{Noun}Tests.cs`
-3. **Test Class Structure**:
-
-```csharp
-using Microsoft.VisualStudio.TestTools.UnitTesting;
-
-namespace PnP.PowerShell.Tests.FeatureArea
-{
-    [TestClass]
-    public class VerbPnpNounTests
-    {
-        [TestMethod]
-        public void TestMethodName()
-        {
-            // Arrange
-            // Act
-            // Assert
-        }
-    }

+9. **Backward Compatibility**: When renaming a cmdlet or fixing a typo in a cmdlet name, always add an `[Alias()]` attribute with the old cmdlet name to maintain backward compatibility. Example:
+   ```csharp
+   [Cmdlet(VerbsCommon.Get, "PnPEntraIDAppSitePermission")]
+   [Alias("Get-PnPAzureADAppSitePermission")]
+   public class GetEntraIDAppSitePermission : PnPGraphCmdlet
+   ```

 ✅ Add examples to documentation
 ✅ Use PipeBind classes for flexible parameter input
 ✅ Handle errors gracefully with meaningful messages
-✅ Write unit tests for new cmdlets
 ✅ Use existing helper methods and utilities from base classes
 ✅ Follow the existing code structure and patterns
-✅ Test on multiple platforms when possible (Windows, Linux, macOS)
 ✅ Use `ClientContext.ExecuteQueryRetry()` instead of `ExecuteQuery()` for resilience
+✅ Add `[Alias()]` attribute when renaming cmdlets to maintain backward compatibility
