Add your site by contacting the ring maintainer via tar@tar.dev.
Provide your site URL in the message, e.g.:
"Hello! I want to join DevRing! My website is: https://yourdomain.com. I have added the navigation links"
Ensure easily accessible webring links are placed on your site:
<a href="https://tar.dev/webring/devring/previous?via=https://yourdomain.com">← previous </a>
<a href="https://www.tar.dev/webring/join.php"> DevRing </a>
<a href="https://tar.dev/webring/devring/random"> | random | </a>
<a href="https://tar.dev/webring/devring/next?via=https://yourdomain.com"> next →</a>
Replace yourdomain.com with your actual domain, the same as in your letter to the maintainer. Feel free to stylize the links as you please, but keep them visible.
