+# Arch / AUR Packaging
+
+The draft package name is `tnt-chat` because `tnt` is already a likely name
+collision in Arch/AUR contexts.
+
+## Local validation
+
+From this directory:
+
+```sh
+makepkg -si
+```
+
+Optional package linting:
+
+```sh
+namcap PKGBUILD
+namcap tnt-chat-*.pkg.tar.zst
+```
+
+## Updating metadata
+
+After editing `PKGBUILD`, regenerate `.SRCINFO`:
+
+```sh
+makepkg --printsrcinfo > .SRCINFO
+```
+
+Before AUR submission, replace `sha256sums=('SKIP')` with the real release
+archive checksum, then run the project-level strict check:
+
+```sh
+make release-check-strict
+```
+
+## Manual AUR submission
+
+```sh
+git clone ssh://aur@aur.archlinux.org/tnt-chat.git aur-tnt-chat
+cp PKGBUILD .SRCINFO aur-tnt-chat/
+cd aur-tnt-chat
+git add PKGBUILD .SRCINFO
+git commit -m "Update to 1.0.0"
+git push
+```
+
+Do not wire this to automatic deployment or release automation.
