+# PKGBUILDS
+
+Automated `-bin` packages for the [AUR](https://aur.archlinux.org), kept up to
+date by GitHub Actions.
+
+Every 6 hours the [update workflow](.github/workflows/update.yml) checks each
+package's upstream for a new release. When one is found it:
+
+1. builds the software in an Arch Linux container,
+2. publishes the resulting install tree as a `.tar.zst` asset on a GitHub
+   release of **this** repository (tag `<pkgname>-<version>`),
+3. updates the `PKGBUILD` (pkgver/pkgrel/sha256sums), test-builds it with
+   `makepkg` and regenerates `.SRCINFO`,
+4. commits the changes back to this repository, and
+5. pushes `PKGBUILD` + `.SRCINFO` to the AUR.
+
+The AUR packages themselves only download the prebuilt asset from step 2, so
+users don't need any build dependencies.
+
+## Packages
+
+| Package | Upstream | AUR |
+|---|---|---|
+| `timetable-bin` | [ostfriese4/untis](https://codeberg.org/ostfriese4/untis) — "Timetable", a GTK4 + LibAdwaita client for WebUntis | [timetable-bin](https://aur.archlinux.org/packages/timetable-bin) |
+
+## Setup (one-time)
+
+1. Create an [AUR account](https://aur.archlinux.org/register) and add an SSH
+   public key to it (AUR account settings).
+2. Add the matching **private** key as a repository secret named
+   `AUR_SSH_PRIVATE_KEY`
+   (Settings → Secrets and variables → Actions → New repository secret).
+3. Optionally set the repository **variables** `AUR_GIT_NAME` and
+   `AUR_GIT_EMAIL` to control the commit identity used on the AUR
+   (defaults: `Felitendo` / `95575686+Felitendo@users.noreply.github.com`).
+
+The first push to `ssh://aur@aur.archlinux.org/<pkgname>.git` creates the AUR
+package automatically.
+
+## Adding a package
+
+Create a new directory named after the AUR package containing:
+
+- **`PKGBUILD`** — sources the prebuilt asset from
+  `https://github.com/Felitendo/PKGBUILDS/releases/download/<pkgname>-<pkgver>/<pkgname>-<pkgver>.tar.zst`.
+  `pkgver`, `pkgrel` and `sha256sums` are maintained by CI.
+- **`pkg.sh`** — bash sourced by [scripts/update-package.sh](scripts/update-package.sh),
+  providing:
+  - `BUILD_DEPS` — array of Arch packages installed before building,
+  - `latest_version` — prints the latest upstream version (no `v` prefix),
+  - `build_artifact <version> <output-file>` — downloads/builds upstream and
+    writes the install tree (a tarball containing `usr/`) to `<output-file>`.
+
+The workflow discovers package directories automatically. Trigger a run
+manually via *Actions → Update AUR packages → Run workflow* to publish it
+immediately.
