Edit config.yml

There are several ways to edit your CircleCI config.yml file:

Using the CircleCI In-App Configuration Editor

CircleCI provides a built-in configuration editor that allows you to modify your configuration files directly in the web app:

1. In the CircleCI web UI, select a pipeline in the Dashboard's All Pipelines view
2. Select your desired branch from the "All Branches" drop-down menu
3. Click the "Edit Config" button to access the configuration editor

The in-app editor offers helpful features like:

• Automatic validation and error checking
• Auto-complete suggestions
• Configuration tooltips
• Links to relevant documentation

After making changes, you can commit directly to your branch or create a new branch using the "Save and Run" button.

Using VS Code Extension

CircleCI offers a Visual Studio Code extension that provides:

• Real-time syntax validation
• Highlighting and autocomplete suggestions
• Ability to visualize and manage pipelines directly from your code editor

The extension is available on the VS Code marketplace.

Editing Locally

You can also edit the .circleci/config.yml file directly in your local repository:

1. Create or modify the file in your project's .circleci directory
2. Validate your configuration using the CircleCI CLI with circleci config validate
3. Commit and push your changes to trigger a new pipeline

Remember that the config.yml file should be placed in a .circleci directory at the root of your repository. After editing, you can validate your configuration to ensure there are no syntax errors before committing.
