```yaml workflow.yml icon="file-code" theme={"theme":{"light":"github-light","dark":"dracula"}}
name: my-workflow
jobs:
  my-job:
    name: my-job
    runs-on: ubuntu-latest
    steps:
      # ...
      - uses: actions/checkout@v4
      - uses: oven-sh/setup-bun@v2 # [!code ++]

      # run any `bun` or `bunx` command
      - run: bun install # [!code ++]
      - run: bun index.ts # [!code ++]
