## LinkedIn

- Write and publish articles:
  https://www.linkedin.com/help/linkedin/answer/a522427/publish-articles-on-linkedin

LinkedIn supports long-form articles for members and eligible Page admins. Treat current UI/publishing specifics as version-sensitive and verify before giving exact UI instructions.

## Usage rule

These are style/platform references, not substitutes for subject-matter sources.

For the factual content of an article, use the strongest current domain-specific primary sources.
