# Install Preparation

### 1. Download the Dorg Installer and the License file

From the [**Dorg Agency**](https://portal.dorg.pro/), after the purchase of a Dorg, you will be able to download the Dorg Installer application (`Dorg-3-x-Installer-v1.y.z-x64.exe`) and the Dorg license file.

The Dorg installer is currently available only for Windows.

### 2. Install prerequisites

The installer needs the following tools to be installed on the local machine:

* Node JS (version 20.20.0 or newer)\
  <https://nodejs.org/en/download>
* Azure CLI (version 2.40.0 or newer)\
  <https://learn.microsoft.com/en-us/cli/azure/install-azure-cli-windows>
* Pulumi CLI (version 3.220.0 or newer)\
  <https://www.pulumi.com/docs/get-started/download-install/>

After installation, open a PowerShell or Command Prompt window and verify all three tools are in your PATH and meet the minimum versions:
\
`node --version`
\
`az --version`
\
`pulumi version`

After checking prerequisites, launch `az login` to properly login into your Azure subscription.

### 3. Collect other required information

Here are the other information you need to collect in order to run the installer:

* Your Azure Subscription ID (a GUID, visible in Azure Portal → Subscriptions)
* The Resource Group name (created in the Azure Preparation step)
* The Dorg user email address (created in the Azure Preparation step)
* The DNS base domain where the Dorg services will be hosted (e.g. .mycompany.com)
* A stack name for your Dorg installation — a unique identifier using only lowercase letters, numbers, and hyphens (e.g. dorg-)
* The License file downloaded from the Dorg Agency
* The Anthropic API Key (sk-ant-…) generated in the Claude Account step
* The Anthropic Admin API Key (sk-ant-admin-…) generated in the Claude Account step

## 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.dorg.pro/install-dorg/install-a-new-dorg/install-preparation.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.
