+# Ho to use the Web API version
+This Installation adds all HopFrame [endpoints](./endpoints.md) and [services](./services.md) to the application.
+
+1. Add the HopFrame.Api library to your project:
+
+   ```
+   dotnet add package HopFrame.Api
+   ```
+
+2. Create a [DbContext](../database.md) that inherits the ``HopDbContext`` and add a data source
+
+3. Add the HopFrame services to your application, provide the previously created `DatabaseContext` that inherits from `HopDbContextBase`
+
+   ```csharp
+   builder.Services.AddHopFrame<DatabaseContext>();
+   ```
