# Connecting to PostgreSQL

Connect [Publisher](https://github.com/DNAstack/dnastack-product-docs/blob/main/docs/publisher/data-sources/connectors/broken-reference/README.md) to [PostgreSQL](https://www.postgresql.org/docs/) databases to access and share your data. This connection requires your PostgreSQL database credentials and connection details.

## Prerequisites

Before beginning, gather these database details:

* Username
* Password
* Host name
* Port number
* Database name

## Configuration Process

### Initial Setup

From the Publisher interface, select "Data Sources" in the navigation bar and click "Connect Data Source". Choose "PostgreSQL Database" from the available connectors.

### Database Configuration

Enter your PostgreSQL connection details:

* Database username and password
* Host name
* Port number (default is typically 5432)
* Database name
* Enable TLS if required for your connection

{% hint style="warning" %}
Ensure your database user has appropriate permissions for the data you wish to access and that your network security settings allow the connection.
{% endhint %}

### Finalizing Setup

1. Provide a descriptive name for your data source
2. Optionally create and share a collection
