+Track remaining package manager channels. Each tier reflects expected maintenance commitment from the core team.
+
+## Tier 1 — Official (core team maintains)
+
+- [ ] **npx / pnpm dlx** — zero-install via the npm package already published; document the one-liner: \`npx openhuman@latest\`
+- [ ] **Scoop (Windows)** — needs a Windows binary (un-comment the Windows matrix in \`release.yml\` first); add a \`tinyhumansai/scoop-openhuman\` bucket
+
+## Tier 2 — Community-supported (PRs welcome, core team reviews)
+
+- [ ] **AUR (Arch Linux)** — add \`PKGBUILD\` pointing at the GitHub release tarball; list in \`packages/\`
+- [ ] **Nix / nixpkgs** — upstream a \`pkgs/tools/openhuman/default.nix\` derivation; document local flake overlay as interim
+
+## Tier 3 — Planned (no timeline)
+
+- [ ] **Snap / Snapcraft** — \`snapcraft.yaml\`, publish to Snap Store
+- [ ] **Flatpak** — \`org.tinyhumans.Openhuman.yaml\`, publish to Flathub
+- [ ] **WinGet** — manifest in \`microsoft/winget-pkgs\` once Windows binary is stable
+
+## Acceptance criteria
+
+- [ ] Each official channel has a CI smoke test (install + \`openhuman --version\`)
+- [ ] Install commands appear in \`docs/install.md\`
+- [ ] Checksums shipped for all artifacts

+# Installing OpenHuman
+
+## Quick install
+
+| Package manager | Command | OS |
+|---|---|---|
+| **Homebrew** | `brew install tinyhumansai/openhuman/openhuman` | macOS, Linux |
+| **apt** | `sudo apt install openhuman` (see [setup](#apt-debianubuntu)) | Debian, Ubuntu |
+| **npm** | `npm install -g openhuman` | Any (Node ≥ 18) |
+| **curl** | `curl -fsSL https://raw.githubusercontent.com/tinyhumansai/openhuman/main/scripts/install.sh \| bash` | macOS, Linux |
+
+---
+
+## Homebrew (macOS / Linux)
+
+```bash
+brew install tinyhumansai/openhuman/openhuman
+```
+
+**Update:**
+```bash
+brew upgrade openhuman
+```
+
+**Uninstall:**
+```bash
+brew uninstall openhuman
+brew untap tinyhumansai/openhuman   # optional: remove tap
+```
+
+Homebrew installs the binary as `openhuman`. The tap lives at
+[tinyhumansai/homebrew-openhuman](https://github.com/tinyhumansai/homebrew-openhuman).
+
+---
+
+## apt (Debian / Ubuntu)
+
+### 1. Add the repository key and source
+
+```bash
+sudo apt-get install -y gnupg2 curl ca-certificates
+
+curl -fsSL https://tinyhumansai.github.io/openhuman/apt/KEY.gpg \
+  | sudo gpg --dearmor -o /etc/apt/keyrings/openhuman.gpg
+
+echo "deb [signed-by=/etc/apt/keyrings/openhuman.gpg arch=amd64] \
+  https://tinyhumansai.github.io/openhuman/apt stable main" \
+  | sudo tee /etc/apt/sources.list.d/openhuman.list
+```
+
+> **arm64:** replace `arch=amd64` with `arch=arm64` or `arch=amd64,arm64`.
+
+### 2. Install
+
+```bash
+sudo apt-get update
+sudo apt-get install openhuman
+```
+
+**Update:**
+```bash
+sudo apt-get update && sudo apt-get upgrade openhuman
+```
+
+**Uninstall:**
+```bash
+sudo apt-get remove openhuman
+# remove repository (optional):
+sudo rm /etc/apt/sources.list.d/openhuman.list /etc/apt/keyrings/openhuman.gpg
+```
+
+---
+
+## npm
+
+```bash
+npm install -g openhuman
+```
+
+**Update:**
+```bash
+npm update -g openhuman
+```
+
+**Uninstall:**
+```bash
+npm uninstall -g openhuman
+```
+
+The npm package is a thin wrapper that downloads the platform-native binary on
+first install and verifies its SHA-256 checksum before placing it. Node.js ≥ 18
+is required; the binary itself has no Node dependency at runtime.
+
+---
+
+## curl / manual install
+
+```bash
+curl -fsSL \
+  https://raw.githubusercontent.com/tinyhumansai/openhuman/main/scripts/install.sh \
+  | bash
+```
+
+Pass `--dry-run` to preview actions without installing:
+
+```bash
+bash scripts/install.sh --dry-run --verbose
+```
+
+**Uninstall (manual):**
+```bash
+rm "$(which openhuman)"
+```

+
+---
+
+## Troubleshooting
+
+### macOS Gatekeeper warning
+
+If macOS blocks the binary with *"cannot be opened because the developer cannot be verified"*:
+
+```bash
+# Option 1: approve via System Settings → Privacy & Security → Allow Anyway
+# Option 2: remove quarantine flag (Homebrew install should handle this automatically)
+xattr -d com.apple.quarantine "$(which openhuman)"
+```
+
+Binaries installed via Homebrew or the signed `.app` bundle are notarized by
+Apple and should not trigger Gatekeeper.
+
+### apt: "NO_PUBKEY" error
+
+Re-import the key:
+```bash
+curl -fsSL https://tinyhumansai.github.io/openhuman/apt/KEY.gpg \
+  | sudo gpg --dearmor -o /etc/apt/keyrings/openhuman.gpg
+sudo apt-get update
+```
+
+### npm: binary not found after install
+
+The postinstall script may have failed silently. Re-run it manually:
+```bash
+FORCE_REINSTALL=1 node "$(npm root -g)/openhuman/install.js"
+```
+
+Or reinstall cleanly:
+```bash
+npm uninstall -g openhuman && npm install -g openhuman
+```
+
+### Verify checksum manually
+
+Every release asset ships a companion `.sha256` file:
+
+```bash
+VERSION=0.49.33
+TARGET=x86_64-unknown-linux-gnu
+curl -fsSLO "https://github.com/tinyhumansai/openhuman/releases/download/v${VERSION}/openhuman-core-${VERSION}-${TARGET}.tar.gz"
+curl -fsSLO "https://github.com/tinyhumansai/openhuman/releases/download/v${VERSION}/openhuman-core-${VERSION}-${TARGET}.tar.gz.sha256"
+echo "$(cat openhuman-core-${VERSION}-${TARGET}.tar.gz.sha256)  openhuman-core-${VERSION}-${TARGET}.tar.gz" | sha256sum --check
+```
+
+---
+
+## Release artifacts reference
+
+Each release attaches the following files:
+
+| Artifact | Platform |
+|---|---|
+| `openhuman-core-<v>-aarch64-apple-darwin.tar.gz` | macOS Apple Silicon |
+| `openhuman-core-<v>-x86_64-apple-darwin.tar.gz` | macOS Intel |
+| `openhuman-core-<v>-x86_64-unknown-linux-gnu.tar.gz` | Linux x86-64 |
+| `openhuman-core-<v>-aarch64-unknown-linux-gnu.tar.gz` | Linux arm64 |
+| `OpenHuman_<v>_aarch64.dmg` | macOS desktop app (Apple Silicon) |
+| `OpenHuman_<v>_x64.dmg` | macOS desktop app (Intel) |
+| `OpenHuman_<v>_amd64.deb` | Linux desktop app (.deb) |
+| `OpenHuman_<v>_amd64.AppImage` | Linux desktop app (AppImage) |
+
+Every archive has a corresponding `.sha256` companion file.
