How to federate via Bridgy Fed

Status: works today. Bridgy Fed needs only microformats2 + a feed (and rel=me), all of which colophon already emits — no colophon code beyond what's shipped.

Bridgy Fed makes your site itself followable from Mastodon and Bluesky: people follow @yourdomain, your posts federate, and replies come back as webmentions — without you running an ActivityPub server or even having a Mastodon/Bluesky account.

Steps

Publish your site with colophon as usual. It already emits:
- h-entry/h-card/h-feed microformats2, an RSS/Atom/JSON feed, and rel="me" identity links. An author's rel="me" (all of their urls:) is emitted in the <head> of their posts and their author feed page (/authors/<id>/) — your IndieWeb identity URL is that author page, not the bare domain (the home page lists every author, so it carries no single identity).
Add a webmention endpoint pointing at Bridgy Fed so it can receive interactions for you:
```
federation:
  indieweb:
    webmention:
      receiver: https://fed.brid.gy/webmention   # emitted as <link rel="webmention"> on every page
```
colophon emits the <link rel="webmention"> discovery tag site-wide when receiver is set — no manual theme edit needed.
Enrol at https://fed.brid.gy and follow its current instructions for your domain (it verifies your site, then your handle becomes @yourdomain@yourdomain). Bridgy Fed's onboarding changes over time, so use its docs as the source of truth: https://fed.brid.gy/docs.
Done. Fediverse/Bluesky users can follow you; new posts federate from your feed; replies arrive at the webmention endpoint (see Show webmentions to display them).

Notes

This is federation, not syndication: there's no separate silo account — your site is the account. For posting copies to your own Mastodon/Bluesky accounts instead, see the syndication guides.
Forward-only is fine: you can be followable without displaying replies; add webmention display when you want the conversation on your page.
