# Upgradability

The platform is designed by a set of registries where the component itself can't be updated but can be replaced by a new version. Clients of these components will automatically switch to the latest version of it. The core part of the platform ("Silo") does not store any information regarding the version of such components as price providers or tokens factory. It fetches the latest version from the Silo repository before any request to these components. The only component in the system that can't be updated is Silo Repository.

## 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://devdocs.silo.finance/protocol-architecture/upgradability.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.
