+As you can see, pipelines are defined by jobs, and functions usually represent jobs. You can define as many jobs in your pipeline as you want.
 
 At the end, we define a jobs array that populates all jobs to gaia. We also add some information like a title, a description and the priority.
 
-The priority is really important and should always be used. If, for example, job A has a higher priority (decimal number) as job B, job A will be executed **after** job B. Priority defines therefore the order of execution. If two or more jobs have the same priority, those will be executed simultanously. You can compare it with the `Unix nice level`_.

 That's it! Put this code into a git repository and create a new pipeline via the gaia UI.
 Gaia will compile it and add it to it's store for later execution.
