In this article, you'll learn how to create and run [machine learning pipelines](concept-ml-pipelines.md) by using the Azure Machine Learning studio and [Components](concept-component.md). You can create pipelines without using components, but components offer better amount of flexibility and reuse. Azure Machine Learning Pipelines may be defined in YAML and [run from the CLI](how-to-create-component-pipelines-cli.md), [authored in Python](how-to-create-component-pipeline-python.md), or composed in Azure Machine Learning studio Designer with a drag-and-drop UI. This document focuses on the Azure Machine Learning studio designer UI.

## Register component in your workspace

To build pipeline using components in UI, you need to register components to your workspace first. You can use UI, CLI or SDK to register components to your workspace, so that you can share and reuse the component within the workspace. Registered components support automatic versioning so you can update the component but assure that pipelines that require an older version continues to work.

The example below uses UI to register components, and the [component source files](https://github.com/Azure/azureml-examples/tree/main/cli/jobs/pipelines-with-components/basics/1b_e2e_registered_components) are in the `cli/jobs/pipelines-with-components/basics/1b_e2e_registered_components` directory of the [`azureml-examples` repository](https://github.com/Azure/azureml-examples). You need to clone the repo to local first.

This example uses `train.yml` [in the directory](https://github.com/Azure/azureml-examples/tree/main/cli/jobs/pipelines-with-components/basics/1b_e2e_registered_components). The YAML file defines the name, type, interface including inputs and outputs, code, environment and command of this component. The code of this component `train.py` is under `./train_src` folder, which describes the execution logic of this component. To learn more about the component schema, see the [command component YAML schema reference](reference-yaml-component-command.md).
