# Step 1: Setting up

First, you've read up on the [role of the DPO](https://www.dastra.eu/fr/guide/les-missions-du-dpo/51090) and the requirements for appointing a DPO, then you decide whether or not to [appoint a DPO](https://www.dastra.eu/fr/guide/les-modalites-de-designation-dun-delegue-a-la-protection-des-donnees/42392) in your organization.

Your choice will be an employee (DPO or not) who, in turn, will define and lead a network of GDPR correspondents within the company's various businesses.

{% hint style="info" %}
The appointment of a Data Protection Officer (DPO) is **mandatory** for:

* Public organizations ;
* Companies whose core business involves large-scale, regular and systematic tracking of individuals, or large-scale processing of so-called "sensitive" data or data relating to criminal convictions and offenses.

## 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://doc.dastra.eu/en/commencer/tutorial/step-1-setting-up.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.
