+## How to Add Support for a New .NET Version
+In the root folder of the project, there is a PowerShell script named `Add-ExampleVersion.ps1`. It is designed to automate the creation of new example and test projects for a specific .NET version by copying existing ones.
+
+
+The script requires two parameters: `sourceVersion` and `targetVersion`. 
+- `sourceVersion` — the version to copy projects from
+- `targetVersion` — the new version to create projects for
+
+Example of calling the script:
+```powershell
+.\Add-ExampleVersion.ps1 -sourceVersion 7.0 -targetVersion 10.0
+```
+
+### Steps to update:
+1. Run the script as shown above;
+1. In each `.csproj` (`Core` and `Identity`) file, update the `TargetFrameworks` element to include the new version;
+1. Update the `Version` field if needed;
+1. Review and update NuGet package dependencies in `<ItemGroup>` sections;
+1. Run tests locally to verify everything works as expected.
