7. Write next to the class file `: IMod` and import the required namespace `by using KS.Modifications;`. You should see errors indicating that you have to implement the methods.

9. Remove all calls to `NotImplementedException` and set the minimum supported API version. Currently, we're at `v3.0.25.377`.

10. Now, implement everything as you wish. Once you're done, follow the steps on how to create a strong name signing key and [sign your mod](https://learn.microsoft.com/en-us/dotnet/standard/assembly/sign-strong-name). Then, click on the `Build` menu and select `Build Solution`.

11. Once the solution is built, open the file explorer to the solution directory by right-clicking on the solution and selecting `Open Folder in File Explorer`.

You will have to turn on kernel modifications from the kernel settings. Navigate to `General > Start kernel modifications on boot` and turn it on.

You can also make use of the [`KSTemplates`](https://github.com/Aptivi/KSTemplates) repository, which can be installed to Visual Studio using the `dotnet new install path/to/KS.Templates.nupkg` command.
