+# Packaging
+
+This directory contains package-manager drafts for TNT. They are intentionally
+kept out of the root install path and should be reviewed before submission to
+any public registry.
+
+## Current targets
+
+- `arch/PKGBUILD` - AUR-ready draft for `tnt-chat`.
+- `homebrew/tnt-chat.rb` - Homebrew tap formula draft.
+- `debian/README.md` - Ubuntu PPA / Debian packaging notes.
+
+## Release checklist
+
+1. Confirm `TNT_VERSION` in `include/common.h` and the manpage version match.
+2. Create a GitHub release tag such as `v1.0.0`.
+3. Build and upload release tarballs or rely on GitHub source archives.
+4. Replace placeholder checksums in package drafts.
+5. Verify package contents in an isolated directory:
+
+   ```sh
+   make clean
+   make
+   tmpdir="$(mktemp -d)"
+   make DESTDIR="$tmpdir" PREFIX=/usr install
+   find "$tmpdir" -type f | sort
+   ```
+
+6. Submit packages manually:
+   - Arch: upload `PKGBUILD` and generated `.SRCINFO` to AUR.
+   - Homebrew: open a PR to the project tap, or later Homebrew core if eligible.
+   - Ubuntu: build Debian source packages and upload to a Launchpad PPA.
+
+Do not connect these packaging drafts to automatic production deployment.

+# Debian and Ubuntu Packaging
+
+Ubuntu distribution should start with a Launchpad PPA. Direct inclusion in
+Debian or Ubuntu archives is a separate, slower process and should wait until
+the project has a stable release cadence.
+
+## Recommended path
+
+1. Keep the upstream project installable with:
+
+   ```sh
+   make DESTDIR="$pkgdir" PREFIX=/usr install
+   ```
+
+2. Create Debian packaging metadata from a release tarball:
+
+   - `debian/control`
+   - `debian/rules`
+   - `debian/changelog`
+   - `debian/copyright`
+   - `debian/install`
+   - optional `debian/tnt.service`
+
+3. Build locally with `debuild` or `dpkg-buildpackage`.
+4. Upload the signed source package to a Launchpad PPA.
+5. Only after repeated stable releases, consider Debian mentors or Ubuntu
+   archive sponsorship.
+
+## Package shape
+
+- Binary package name: `tnt-chat`
+- Installed command: `/usr/bin/tnt`
+- Runtime dependency: `libssh`
+- Optional systemd unit: `/usr/lib/systemd/system/tnt.service`
