Steps and Workflows are the heart of how Bitrise works. A Bitrise build is simply a series of Steps, defined in a Workflow, executed by the Bitrise CLI on our virtual machines (or your own).
A Step contains the code that performs the build task. You can configure the inputs and parameters that define the task, and view and reuse the outputs a Step generates.
When a build of an app is running, the Steps will be executed in the order that is defined in the Workflow.
You can easily move Steps around in a Workflow, you can chain different Workflows together, and you can configure your app so that different branches or code events trigger builds with different Workflows.
