-This document contains a procedure that enables you to upload a CSV file containing data to Amazon S3, where it uses Lambda to automatically parse, format, and upload the data to Segment.
+This document outlines how to upload a CSV file containing data to [Amazon S3](https://aws.amazon.com/s3/){:target="_blank”}, which uses [Lambda](https://aws.amazon.com/lambda/){:target="_blank”} to automatically parse, format, and upload the data to Segment.
 
 You might have sources of data where you can't instrument Segment's SDKs, including other SaaS tools for which a Segment integration is not yet available. In many of these cases, you can extract data from these sources in CSV format, and then use Segment's server-side SDKs or HTTP tracking API to push the data to Segment.
