# Repository Database
When setting up the repository database for MailScheduler, it's crucial to understand that the database driver cannot be changed after the initial setup. Make sure to select the appropriate driver during the initial configuration to avoid any future complications.
{% hint style="danger" %}
We do **not** recommend changing the repository database. Only when your credentials change you can use this page. When changing the database we recommend doing a fresh installation.

## 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.infotopics.com/mailscheduler/configuration/one-click/repository-database.md?ask=&goal=
```
`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.
