# This defines the name of the workflow as it will appear in the "Actions" tab of the GitHub repository.

# The `on` keyword lets you define the events that trigger when the workflow is run. You can define multiple events here. For more information, see "[AUTOTITLE](/actions/using-workflows/triggering-a-workflow#using-events-to-trigger-workflows)."
on:

  # Add the `workflow_dispatch` event if you want to be able to manually run this workflow. For more information, see [`workflow_dispatch`](/actions/using-workflows/events-that-trigger-workflows#workflow_dispatch).
  workflow_dispatch:

  # Add the `pull_request` event, so that the workflow runs automatically every time a pull request is created or updated. For more information, see [`pull_request`](/actions/using-workflows/events-that-trigger-workflows#pull_request).
  pull_request:

  # Add the `push` event with the `branch` filter, so that the workflow runs automatically every time a commit is pushed to a branch called "main". For more information, see [`push`](/actions/using-workflows/events-that-trigger-workflows#push).

# The `concurrency` key ensures that only a single workflow in the same concurrency group will run at the same time. For more information, see "[AUTOTITLE](/actions/using-jobs/using-concurrency)."
# `concurrency.group` generates a concurrency group name from the workflow name and pull request information. The `||` operator is used to define fallback values.
# `concurrency.cancel-in-progress` cancels any currently running job or workflow in the same concurrency group.

    # In this example, the job will run on a self-hosted runner if the repository is named `docs-internal` and is within the `github` organization. If the repository doesn't match this path, then it will run on an `ubuntu-latest` runner hosted by GitHub.

      # The `uses` keyword tells the job to retrieve the action named `actions/checkout`. This is an action that checks out your repository and downloads it to the runner, allowing you to run actions against your code (such as testing tools). You must use the checkout action any time your workflow will use your repository's code. Some extra options are provided to the action using the `with` key.

      # This step uses the `trilom/file-changes-action` action to gather the files changed in the pull request, so they can be analyzed in the next step. This example is pinned to a specific version of the action, using the `a6ca26c14274c33b15e6499323aac178af06ad4b` SHA.

      # This step uses the `actions/cache` action to cache the Next.js build, so that the workflow will attempt to retrieve a cache of the build, and not rebuild it from scratch every time. For more information, see "[AUTOTITLE](/actions/using-workflows/caching-dependencies-to-speed-up-workflows)."
