+
+**Front-end libraries** (CSS/JS frameworks like Bootstrap, jQuery, etc.):

+```sh
+dotnet tool restore
+```
+
+Then install front-end libraries using LibMan:
+```sh
+dotnet tool run libman install <library>@<version> --provider cdnjs --destination wwwroot/lib/<library>

+```sh
+dotnet tool run libman install bootstrap@5.3.0 --provider cdnjs --destination wwwroot/lib/bootstrap
+dotnet tool run libman install jquery@3.7.1 --provider cdnjs --destination wwwroot/lib/jquery
+```
+
+**NuGet packages** (C# libraries and frameworks):
+```sh
+dotnet add package <PackageName>
+```

+```sh
+dotnet add package Newtonsoft.Json
+dotnet add package Microsoft.EntityFrameworkCore.SqlServer
+```
