+
+With this connector, Hasura allows you to instantly create a real-time GraphQL API on top of your data models in
+Trino. This connector supports Trino's functionalities listed in the table below, allowing for efficient and
+scalable data operations. Additionally, users benefit from all the powerful features of Hasura’s Data Delivery Network
+(DDN) platform, including query pushdown capabilities that delegate query operations to the database, thereby enhancing
+query optimization and performance.
+
+This connector implements the [Data Connector Spec](https://github.com/hasura/ndc-spec).

+
+## Prerequisites
+
+1. Create a [Hasura Cloud account](https://console.hasura.io)
+2. Please ensure you have the [DDN CLI](https://hasura.io/docs/3.0/cli/installation) and
+   [Docker](https://docs.docker.com/engine/install/) installed
+3. [Create a supergraph](https://hasura.io/docs/3.0/getting-started/init-supergraph)
+4. [Create a subgraph](https://hasura.io/docs/3.0/getting-started/init-subgraph)
+
+The steps below explain how to initialize and configure a connector on your local machine (typically for development
+purposes).You can learn how to deploy a connector to Hasura DDN — after it's been configured —
+[here](https://hasura.io/docs/3.0/getting-started/deployment/deploy-a-connector).
+
+## Using the Trino connector
+
+With the [context set](https://hasura.io/docs/3.0/cli/commands/ddn_context_set/) for an existing subgraph, initialize
+the connector:
+
+```sh
+ddn connector init -i
+```
+
+When the wizard runs, you'll be prompted to enter the following env vars necessary for your connector to function:
+
+| Name     | Description                             | Required |
+| -------- | --------------------------------------- | -------- |
+| JDBC_URL | The JDBC URL to connect to the database | Yes      |
+
+After the CLI initializes the connector, you'll need to:
+
+- [Introspect](https://hasura.io/docs/3.0/cli/commands/ddn_connector_introspect) the source.
+- Add your [models](https://hasura.io/docs/3.0/cli/commands/ddn_model_add),
+  [commands](https://hasura.io/docs/3.0/cli/commands/ddn_command_add), and
+  [relationships](https://hasura.io/docs/3.0/cli/commands/ddn_relationship_add).
+- Create a [new build](https://hasura.io/docs/3.0/cli/commands/ddn_supergraph_build_local).
+- Test it by [running your project along with the connector](https://hasura.io/docs/3.0/cli/commands/ddn_run#examples).
+
+## Example JDBC Configuration
+
+Supposing you have a MySQL datasource `example_mysql` in your Trino instance's catalog, and a database named `chinook`, you might use a JDBC URL of the format:
+- `jdbc:trino://localhost:8080/example_mysql/chinook?user=trino`
+
+Ensure that your MySQL instance in the Trino catalog is configured with `case-insensitive-name-matching=true` for proper SQL query functionalty.
+
+A full example might be:
+```ini
+connector.name=mysql
+connection-url=jdbc:mysql://host.docker.internal:3306
+connection-user=root
+connection-password=Password123
+unsupported-type-handling=convert-to-varchar
+case-insensitive-name-matching=true
+```
