# LinkedIn optimization sources

> This file contains the citations used by the `linkedin` module. Official LinkedIn help pages are the baseline; 360Brew research and third-party examples are secondary sources.

---

## 1. Overview

The rules defined in the `linkedin` module are based primarily on LinkedIn help-center documentation about Feed relevance, people search, profile verification, and skills. 360Brew sources are used to understand the public research debate, not to assert undocumented production behavior.
