1. Build and serve this tests website locally.

  2. Check that both your local build of this website and the theme docs website show the same favicon.

  3. Move favicon.ico to assets/images/.

  4. Check that the favicon has disappeared, and that Jekyll does not report “ERROR ‘/favicon.ico’ not found”.

  5. Set favicon_ico: /assets/images/favicon.ico, then rebuild this website.

  6. Check that the favicon has reappeared.

  7. Move the favicon back to the root directory, and remove the setting of favicon_ico.
