 ## What Does it Mean to Set Up a Marketplace?
 
-An Ocean marketplace app is one of the primary ways that end users use the Ocean network. For example, a data scientist could use a marketplace app to see what data sets and data services (data assets) a marketplace has available. They can use the marketplace app to buy access to assets. Publishers make those data assets available.

For example, a data scientist could use a marketplace app to see what [assets](/concepts/terminology/#asset-or-data-asset) a marketplace has available. They can use the marketplace app to buy access to assets. Publishers make those assets available.
 
 **Note: In the early days of the Ocean network, there won't be many marketplaces or publishers, so marketplaces will often also act as publishers.**
 
 If you want to set up and run a marketplace in the Ocean network, then at a technical level, you must:
 
-1. Have [Data Assets](/concepts/terminology/#asset-or-data-asset) to offer in your marketplace.
-1. Get those data assets set up to work with Ocean Protocol.

+description: Tutorial about how to set up Amazon S3 storage for use with Ocean Protocol.
+---
+
+To enable Brizo to use files stored in Amazon S3 (i.e. files with an URL containing "s3://"), you must:
+
+1. have an Amazon AWS user account (IAM account) with permission to read those files from S3, and
+1. set the AWS credentials on the machine where Brizo is running to those of the AWS user in question. Instructions are given below.
+1. Note that you don't have to set any Brizo-specific configuration settings, e.g. in the `[osmosis]` section of the Brizo config file or in some special Brizo environment variables.
+
+Under the hood, Brizo uses [boto3](https://aws.amazon.com/sdk-for-python/) (the Python library for interacting with AWS) to interact with AWS and boto3 has a whole process for determining AWS credentials. The easiest way to set the AWS credentials on the machine where Brizo is running is to install the [AWS CLI](https://aws.amazon.com/cli/) and then use the `aws configure` command. For more details, see [the boto3 user guide about credentials](https://boto3.amazonaws.com/v1/documentation/api/latest/guide/configuration.html).

+
+To enable Brizo to use files stored in on-premise storage (i.e. files with an URL not containing "core.windows.net" or "s3://"), there is _nothing to do, other than make sure Brizo can resolve the URLs_. In particular, you don't have to set any Brizo-specific configuration settings, e.g. in the `[osmosis]` section of the Brizo config file or in some special Brizo environment variables.

+Local and private network URLs are fine so long as they can be resolved by Brizo. Potential examples include `http://localhost/helicopter_data.xls`, `http://192.168.12.34/almond_sales_2012.csv` and `http://10.12.34.56/duck_photos.zip`.
