# GitHub

{% hint style="info" %}
&#x20;Elixir SDK for Unity is available at <https://github.com/Elixir-Games-XYZ/elixir-unity-sdk>
{% endhint %}

## Existing Git Repositories

This workflow is for games that use `git` as their primary version control system.

### Getting Started

If you are already using `git` as the version control system of choice for your game, you will need to add `ElixirUnitySDK` as a git submodule.

1. Navigate to the `Assets` directory in your game
2. Run:\
   `git submodule add git@github.com:Elixir-Games-XYZ/elixir-unity-sdk.git ElixirUnitySDK`
3. Verify that a file named `.gitmodule` appeared at the root of your game project folder, and that the Elixir SDK for Unity has been correctly pulled into `Assets/ElixirUnitySDK`
4. This change will now be staged for a commit. Commit it by running `git commit` with a message. For example: \
   `git commit -m "Feat: Added Elixir SDK"`

### Cloning

{% hint style="warning" %}
If you do not do this when you clone your game's repository, the submodule will not be correctly initialized
{% endhint %}

Working with git submodules introduces one extra step when cloning your repository on a new machine.

1. Clone your game as usual: \
   `git clone YOUR_GIT_REPO`
2. **NEW STEP:** Initialize the submodules by running: \
   `git submodule update --init --recursive`

### **Pulling**

{% hint style="warning" %}
If you do not pull changes from your repository correctly , the submodule will not be updated
{% endhint %}

To pull in all changes in your repository including changes in submodules you can run:

```bash
git pull --recurse-submodules
```

### Updating Submodule

To fetch the latest changes from the Elixir SDK repository run the following:

```bash
git submodule update --remote
```

You will then be required to commit this change in order to persist the commit of the submodule that your game's repository is pointing to.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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.elixir.app/sdk/unity/getting-started/updates/github.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.
