Code Review

This pull request correctly fixes a broken link in the FEDERATION.md documentation file. I've included one suggestion to improve the phrasing of the sentence containing the link to make it clearer and more descriptive for future readers.

For better readability, consider rephrasing this sentence. Using a more descriptive link text than doc and structuring the sentence more formally would improve the documentation.
