  -The above example is a [command step](), which will run the code `echo "Hello!"` and print "Hello!" to the build's log.

   To test your `.buildkite/pipeline.yml` file, commit your `pipeline.yml` file and push it to your repository. If you've set up webhooks, this will automatically create a new build. You can also create a new build using the 'New Build' button on the pipeline page.

  +If your pipeline has a lot of steps and you have multiple agents available to run them, they will automatically run at the same time. If your steps rely on running in sequence, you can use [wait steps](/docs/pipelines/wait-step) to ensure that the steps before the 'wait' are completed before subsequent steps are run. 
  +
  +When each step is run by an agent, it will be run with a clean checkout of the pipeline's repository. If your commands or scripts rely on the output from previous steps, you will need to either combine them into a single script or use artifacts to pass data between steps. This enables any step to be picked up by any agent and run steps concurrently to speed up your build.

  ## Migrating existing steps to a pipeline.yml
  
  If you have a pipeline that is defined in the web interface and would like to migrate it to a `pipeline.yml` without any interruption to builds, you can add a command step and wait step at the start of your pipeline.
  
  For agents running Linux, macOS or other Unixes, the command is:

  ## Getting started
  
  After creating a [pipeline](https://buildkite.localhost/docs/pipelines), you can add steps in the Buildkite Pipeline Settings. In the 'Steps' section, click the ➕ to add a step. You can create your entire pipeline by adding steps in this way. 
  
  To use a pipeline.yml file, click the ➕ to add a step and select “Read steps from repository”:
