+### Repository pages
+
+Every public GitHub repository has a page on /dev/null at `/github/{owner}/{repo}`, such as `/github/laravel/framework`. It gathers every commit and reply that links to the repository, or to anything in it like an issue, a pull request, or a file, newest first, so you can read what developers here are saying about a project in one place. A `.git` clone URL counts too. Only the link counts: writing `owner/repo` without `github.com` doesn't, and a link to a similarly named repository like `laravel/framework-docs` doesn't either. Names match regardless of case.
+
+The page shows the repository's name, description, and star count as GitHub reports them, refreshed about once a day, plus how many of the commits you can see mention it and how many people wrote them. Private repositories, deleted ones, or a GitHub outage leave out those details but still list the commits. The page follows the usual visibility rules: guests and crawlers can read it, only approved commits show to others, and muted and blocked people are filtered out. For now the page is reached by its address; links in commits still open GitHub.
+
+Sources: [repository page](app/Http/Controllers/RepositoryController.php), [matching commits](app/Queries/RepositoryCommitsQuery.php), [GitHub details](app/Queries/GitHubRepositoryQuery.php), [page](resources/js/pages/repository/show.tsx).

 ### Replies and threads
 
 Reply to a visible commit to continue its thread. Replies use the same text limits, image support, moderation, and submission rate limit as commits. Threads expand inline, a few replies at a time: choose 1, 3, 5, 10, 15, 20, or 25 in Settings → Appearance (3 by default). Opening a commit's own page shows its ancestors and replies. Quotes of a commit are listed among its replies and counted with them. Profiles have a separate Replies tab for authored replies. A reply cannot also be a quote, contain a poll, or be scheduled.
