What are pipelines, jobs & steps ​

• Pipeline: Pipelines are TypeScript files like build.ts, deploy.ts, or run_tests.ts. They are checked into your repository and run when triggered by an event in your repository, or when triggered manually, or at a defined schedule. A pipeline takes one parameter: an array of jobs.
• Jobs: A job is a lightweight container that executes code. It takes one parameter: an array of steps.
• Steps: A step is either a shell script or Deno/TypeScript script that executes in its parent job's container
