# Required Links

In your article settings, you can specify Required Links. Topyc will link to them in the article content.

Simply paste in one url per line (meaning, one url, or a line-separated list of urls).

Topyc visits them, analyzes the content of that page, and uses that to help it decide where and how to link to that page in the generated content.

Useful for specifying internal links, for example.
