# Address Book

The Address Book app makes it easy to assign human-readable names to Ethereum addresses.

{% hint style="info" %}
**Disclaimer**: The Address Book application is designed to act as a new Identity Provider for Aragon Organizations, so you can assign a name to an Ethereum address and have that name be displayed in all of your Aragon apps in place of the address. This requires [an enhancement to aragonSDK](https://github.com/aragon/aragon.js/pull/391), which is scheduled for an upcoming release. We will remove this note once it’s fully available, but until then you can begin naming and categorizing addresses.
{% endhint %}

In the panel, input the name you want to assign to an address. You can label your new entity as either an Individual or an Organization. The Address must be a valid Ethereum address.

## Features coming soon

### **Custom types**

If an entity is neither an individual nor an organization, you can create an entity with a “Custom type”, or in other words, a user-defined category, which can be reused across other entities.

To set up a custom type, the option can be selected from the “Type” dropdown menu. After doing so, an additional input appears right below where you can input the name. After an entity with this type gets created, the type will be reusable.

### ‌**Update an entity**

To make any modifications to an existing entity, click on the menu icon associated to the entity and choose “Update”. This will open a panel where a new "Name" or "Type" can be defined.

## 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://autark.gitbook.io/open-enterprise/apps/address-book.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.
