 This article demonstrates how ClickHouse Cloud customers can leverage role-based access to authenticate with Amazon Simple Storage Service (S3) and access their data securely.
-
-## Introduction {#introduction}
-
 Before diving into the setup for secure S3 access, it is important to understand how this works. Below is an overview of how ClickHouse services can access private S3 buckets by assuming into a role within customers' AWS account.
 
+<br/>
 <Image img={secure_s3} size="md" alt="Overview of Secure S3 Access with ClickHouse"/>
+<br/>
 
 This approach allows customers to manage all access to their S3 buckets in a single place (the IAM policy of the assumed-role) without having to go through all of their bucket policies to add or remove access.
+In the section below, you will learn how to set this up.

 This guide will show how to migrate from a self-managed ClickHouse server to ClickHouse Cloud, and also how to migrate between ClickHouse Cloud services. The [`remoteSecure`](/sql-reference/table-functions/remote) function is used in `SELECT` and `INSERT` queries to allow access to remote ClickHouse servers, which makes migrating tables as simple as writing an `INSERT INTO` query with an embedded `SELECT`.
