 This guide explains how to set up the Snowflake emulator in a continuous integration (CI) environment. You can use the emulator to test your Snowflake integration without connecting to the real Snowflake instance.
 
-To install the Snowflake emulator, you need to set up the LocalStack CLI and pull the Docker image. After starting the Docker container, an endpoint (`snowflake.localhost.localstack.cloud`) is made available to connect to the emulated Snowflake instance, which you can use to test your data integrations in CI environments.
+To install the Snowflake emulator, you need to set up the [`lstk` CLI](/aws/developer-tools/running-localstack/lstk/), which authenticates, pulls the Docker image, and starts the container for you. After starting the Docker container, an endpoint (`snowflake.localhost.localstack.cloud`) is made available to connect to the emulated Snowflake instance, which you can use to test your data integrations in CI environments.
