Add conditions to a workflow

- [Instructor] When we use the push and pull request events … to trigger our workflow, we can limit activity … to specific branches. … To set this up, we need to change our YAML formatting a bit. … Instead of using a value for the on key as we see here, … the event needs to be in its own YAML block. … Basically, we move the event down to the next line … and follow it with a colon to indicate a new block … with its own mapping. … Now we can add the branches conditional … where we can list the branches … we want the workflow to focus on. … For example, if we want pushes to our repo … to only work on the branches named develop and master, … we would add a dash and then list those branch names. … If we want pull requests to only work on our master branch, … we would add a list entry with master … under the pull request attribute. … Now these examples would be for workflows … that only have one trigger, a push or a pull request. … What if we have a workflow … that's triggered by both of these events? …
