Poem

A nibble of docs, a tick of a tag,
I hop through markdown with a jaunty wag.
Backticks snug where angle brackets tread—
Now the page reads neat, just as said.
Thump-thump! Little changes, forward we tread.

Code Review

Summary

This PR fixes a documentation issue where the HTML head tag was not properly escaped in the markdown file, which could confuse MDX parsers. The change escapes the tag using backticks.

Positive Aspects

• Correct fix: Using backticks is the proper way to escape HTML tags in Markdown/MDX
• Minimal change: Only affects the problematic line without unnecessary modifications
• Clear intent: The PR title and change clearly communicate the purpose

Feedback

1. Pull Request Description (Minor): The PR description still contains the template text. Consider filling it out with a brief description and marking checklist items appropriately.

2. CHANGELOG Entry (Consider): Per the project's CLAUDE.md guidelines, documentation fixes typically should be added to the CHANGELOG, though this is a judgment call for very minor doc fixes.

Technical Assessment

• Code Quality: Excellent - proper Markdown escaping
• Potential Bugs: None identified
• Performance: No impact (documentation only)
• Security: No concerns
• Test Coverage: Not applicable (documentation change)

Recommendation

APPROVE with minor suggestions. The core change is correct and ready to merge. The only suggestions are about PR documentation hygiene, which are nice-to-have but not blockers.

Code Review

Summary

This PR fixes a documentation formatting issue where the HTML <head> tag was being rendered as actual HTML instead of displaying as code text in MDX parsers. The change wraps it in backticks to ensure it displays correctly.

✅ Positive Points

• Correct fix: Using inline code backticks (<head>) is the right approach for MDX/Markdown parsers
• Minimal change: Only changes what is necessary
• Clear intent: The PR title and change clearly communicate the purpose

📝 Feedback & Issues

1. PR Description Needs Completion ⚠️

The PR body still contains template placeholders that should be removed/filled:

• "Remove this paragraph and provide a general description..."
• "Remove this line after checking all the items..."
• "Remove this paragraph and mention any other important..."

Suggested description:

### Summary
Fixed MDX parsing issue in the quick-start guide where `<head>` was being interpreted as an HTML tag instead of displaying as literal text. Changed to inline code format (`<head>`) to ensure proper rendering across all documentation viewers.

### Pull Request checklist
- [x] Add/update test to cover these changes - N/A (documentation only)
- [x] Update documentation - This IS the documentation update
- [ ] Update CHANGELOG file

### Other Information
This is a minor documentation fix that improves readability and prevents MDX parser confusion.

2. Missing CHANGELOG Entry ⚠️

According to the project's PR checklist, CHANGELOG updates should be included. While this is a very minor doc fix, for consistency you should add an entry like:

## [Unreleased]
### Documentation
- Fixed MDX rendering of `<head>` tag in quick-start guide. [#1844](https://github.com/shakacode/react_on_rails/pull/1844)

However, I'd understand if maintainers consider this too minor for CHANGELOG.

3. Consider Related Occurrences

You might want to check if there are other similar issues in the documentation where HTML tags need to be escaped.

Code Quality: ✅ Excellent

• Best practices: ✅ Proper Markdown/MDX formatting
• Potential bugs: ✅ None - this fixes a rendering bug
• Performance: ✅ N/A (documentation only)
• Security: ✅ N/A (documentation only)
• Test coverage: ✅ N/A (documentation only, no automated tests needed)

Recommendation

Approve with minor suggestions. The code change itself is perfect. Just update the PR description and consider adding a CHANGELOG entry for completeness.

Great catch on the MDX parsing issue! 🎯
