 ## Release
 
-Homebrew release scaffolding lives in `scripts/brew-release.sh` and
-`deploy/deploy.env.example` (copy to `deploy/deploy.env`, gitignored). The
-formula is a source build (`depends_on "go"`); publishing is a manual step.
+Releases ship through [custard](https://codex.humdrum.me/r/custard) to the
+self-hosted Homebrew tap. Config lives in `.custard.yaml` (source build,
+`depends_on "go"`). To cut a release, push a `release/vX.Y.Z` bookmark:
+
+    jj bookmark create release/v0.1.0 -r @-
+    jj git push --bookmark release/v0.1.0
+
+custard runs the CI checks, archives the ref, renders `Formula/tt.rb`, and
+commits it to the tap. Install requirements (tock, sqlite) live under
+[Requirements](#requirements) — the auto-formula does not repeat them.

-    <<~EOS
-      tt drives the tock time tracker — install tock and put it on PATH:
-        https://github.com/dhth/tock
-      Tested against tock v1.9.8 (report --json / add -s/-e contract).
-
-      tock's sqlite backend is strongly recommended. On the file/markdown
-      backend, editing an entry (a remove-then-re-add) can silently drop
-      tags/notes because tock's report --json may omit them there.
-
-      For history autocomplete, install the sqlite3 CLI (optional):
-        brew install sqlite
-    EOS
-  end

-  test do
-    assert_path_exists bin/"${REPO}"
