[miyoungc]

Summary by CodeRabbit

• Documentation
  • Updated DGX Spark link to point to the correct repository and adjusted callout styling (NOTE → ℹ️ Note, TIP → 💡 Tip).
• Chores
  • Documentation workflow now triggers on README changes so updates to the README will run the docs workflow.

Poem

🐰 I hopped through lines with eager cheer,

ℹ️ Note and 💡 Tip now crisp and clear,
Links wind outward to GitHub's light,
The docs watch README—day and night,
A tiny rabbit nods: "All right!" 🥕

🧹 Nitpick comments (1)

README.md (1)

64-64: Clarify intent: absolute URL with hardcoded /blob/main/ causes version coupling.

The file exists, but using an absolute GitHub URL with /blob/main/ means this link will always point to the latest version on the main branch, regardless of which README version (tag, branch, or release) a user is viewing. Users reading older releases will see instructions for the current main version, which could contain breaking changes or incompatible prerequisites.

Either confirm this is intentional (to always show the latest Spark setup), or consider using a relative link (spark-install.md) to keep documentation consistent with the README version being viewed.

In `@README.md` at line 64, The README currently links the DGX Spark setup with an
absolute GitHub URL containing /blob/main/, which ties readers to the main
branch; either confirm that behavior is intentional or change the link target in
README.md from the absolute URL to a relative link ("spark-install.md") so
readers viewing tagged/branch releases see the matching doc; update the link
text "DGX Spark setup guide" accordingly and ensure any CI/doc tooling still
resolves the relative path.
