# SageMaker Notebook Instance Lifecycle Configuration

An Amazon SageMaker Notebook Instance Lifecycle Configuration lets you define shell scripts that run when a notebook instance is created or started. These scripts can automate setup tasks such as installing packages, configuring environments, or connecting to data sources, ensuring that every notebook instance is consistently prepared for use.
