# Auto Updater

This page describes the automatic plugin updater functionality and what you need to know to use it.

### Enable the Auto Updater <a href="#enable-the-auto-updater" id="enable-the-auto-updater"></a>

By default the plugin checks for plugin updates but doesn't download them. You can enable the download by activating it in the [config.yml](/setup-guide/getting-started/configuration/config.yml.md) by setting `MyPet.Update.Download` to `true`.

The downloaded jar is placed in the server's `update` folder and loaded automatically on the next server start, replacing the running jar in place and renaming it to match the new version (e.g. `MyPet-4.0.0.jar`).

The `In-Background` option controls timing: when `true`, the download runs on a background thread so it doesn't hold up server startup; when `false`, the plugin waits for the download to finish before continuing to boot.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://wiki.mypet-plugin.com/setup-guide/getting-started/systems/auto-updater.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
