+## Updating LavinMQ
+
+1. In `APKBUILD`, set `pkgver` to the new upstream version and reset `pkgrel`
+   to `0`.
+2. Add versioned vendored archives for the locked Shards dependencies and
+   frontend assets. If the new upstream `shard.lock` and the asset rules in its
+   `Makefile` are unchanged, the existing archives can be reused under the new
+   names:
+
+   ```sh
+   cd packaging/alpine/local/lavinmq
+   cp lavinmq-2.10.1-shards.tar.gz lavinmq-<version>-shards.tar.gz
+   cp lavinmq-2.10.1-assets.tar.gz lavinmq-<version>-assets.tar.gz
+   git add -f lavinmq-<version>-shards.tar.gz lavinmq-<version>-assets.tar.gz
+   ```
+
+   When `shard.lock` changes, extract the upstream source, run
+   `shards install --production` in it, and create the shards archive with
+   `tar -czf lavinmq-<version>-shards.tar.gz lib`. If the asset rules change,
+   download the files specified by the new `Makefile` to a staging directory
+   and create `lavinmq-<version>-assets.tar.gz` from that directory's contents.
+3. From the repository root, refresh checksums and build the package:
+
+   ```sh
+   ALPINE_PACKAGE=lavinmq mise run apk:checksum
+   ALPINE_PACKAGE=lavinmq mise run apk:build
+   ```
