TIL markdown supports diagrams these days. Claude Code assisted me with setting up a CI workflow, opened a PR and added a diagram to visualize it

```mermaid
graph LR
A[GitHub Actions] -->|Generate| B[Changelog]
B -->|Attach to| C[Git Tag]
C -->|Trigger| D[Xcode Cloud]
D -->|Extract| E[TestFlight Notes]
```

Which renders into an interactive diagram in Github. So cool!
