Markdown Diff and Merge for Docs Review

Documentation review often happens outside code review: copied drafts, release note edits, support article rewrites, and README updates from multiple teammates. Markdown diff and merge tools make those changes easier to inspect before the final version is committed.

When to diff Markdown

• A teammate rewrites a README section
• Release notes change before launch
• A support article is edited by multiple people
• Generated docs need human review

Merge workflow

1. Compare the old and new drafts first.
2. Identify additions, removals, and rewritten lines.
3. Merge sections into one clean document.
4. Run formatter and lint checks after merging.
5. Preview the merged result before publishing.

Avoiding messy merges

• Keep headings unique.
• Avoid repeated introductions.
• Standardize terminology before final review.
• Preserve code blocks exactly unless the code changed intentionally.

Conclusion

Markdown diff and merge tools reduce review ambiguity when docs change quickly across multiple drafts.
