-Arch packaging
-==============
-
-`PKGBUILD` builds and installs `breadhelp` from source.
-
-## Local build
-
-```bash
-makepkg -si
-```
-
-## Before publishing to [breadway] repo
-
-1. Tag a release on GitHub.
-2. Update `pkgver` to match the tag.
-3. Update `source` to the release tarball URL.
-4. Run `updpkgsums` (or manually set `sha256sums`).
