# Adding New Platforms

## Introduction

This guide provides instructions for adding a new platform. This could include a new .NET version (such as going to .NET 10) or it could be a new runtime (such as KNI).

## 1. Adding a Template

To add a new template, open the Templates folder and copy an existing template, or add a new project from scratch. Note that the Game1 will get copied over so the contents of Game1 do not matter, and should not differ per platform. If certain platforms (like iOS) require custom code in Game1, you need to add #if blocks.

## 2. Modifying Game1Copier

Open Game1Copier.sln and find Program.cs.

Add information about the newly-created template to the templates list. Rebuild the project, then copy the built .exe to root Templates folder so the new template is copied.

## 3. Modifying BuildServerUploader

Open BuildServerUploader.cs and modify AllData.cs to add the new engine.

## 4. Modifying Glue

Update EmptyTemplates.cs to include the new template.

## 5. Update Engine.yml

Add the NuGet package building steps

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.flatredball.com/flatredball/contributing/adding-new-platforms.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
