# Getting started

{% hint style="info" %}
This page was generated from content adapted from the [AWS Developer Guide](https://github.com/awsdocs/aws-resource-access-manager-user-guide.git)

## Terms and concepts

* **Note**\
  This policy uses `"Principal": "*"` and then uses the `"Condition"` element to restrict permissions to identities that match the specified `PrincipalOrgID`. For more information, see [Implications of using "Principal": "\*" in a resource-based policy](#term-principal-star).

## Sharing your resources

* **Important**\
  You must enable sharing with AWS Organizations by using the AWS RAM console or the [enable-sharing-with-aws-organization](https://docs.aws.amazon.com/cli/latest/reference/ram/enable-sharing-with-aws-organization.html) AWS CLI command. This ensures that the `AWSServiceRoleForResourceAccessManager` service-linked role is created. If you enable trusted access with AWS Organizations by using the AWS Organizations console or the [enable-aws-service-access](https://docs.aws.amazon.com/cli/latest/reference/organizations/enable-aws-service-access.html) AWS CLI command, the `AWSServiceRoleForResourceAccessManager` service-linked role isn't created, and you can't share resources within your organization.
* **Considerations**
* **Note**\
  To obtain the unique ARN for an IAM user, [view the list of users in the IAM console](https://console.aws.amazon.com/iamv2/home?#/users), use the <https://docs.aws.amazon.com/cli/latest/reference/iam/get-user.html> AWS CLI command, or the <https://docs.aws.amazon.com/IAM/latest/APIReference/API_GetUser.html> API action.
* **Note**\
  If you want to use a customer managed permission with a resource type in this resource share, you can either use an existing customer managed permission or create a new customer managed permission. Make note of the ARN for the customer managed permission, and then create the resource share. For more information, see [Create a customer managed permission](https://github.com/kevinslin/aws-reference-notes/blob/main/services/aws_resource_access_manager_aws_ram/create-customer-managed-permissions.md#create_cmp).

## 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://awsnotes.dendron.so/security-identity-and-compliance/aws-resource-access-manager-aws-ram/common/getting-started.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.
