+## [1.2.0] - 2026-04-09
+
+Installer robustness overhaul and one-command bootstrap.
+
+### Added
+
+- **`get.sh`** — one-command bootstrap: `curl -fsSL .../get.sh | bash`
+  - Installs `git` if missing (apt / pacman / dnf / brew)
+  - Clones repo to `~/.vim`; `git pull` if already present
+  - `exec bash install.sh </dev/tty` — interactive prompts work correctly even when piped from curl
+- **Network connectivity check** — warns early if `github.com` is unreachable
+- **`curl` preflight** — detects missing curl, auto-installs or dies with clear instructions
+- **`git` preflight** — same as curl
+- **`vim` auto-install** — attempts `pkg_install` before dying if vim is not found
+- **`sudo` availability check** — authenticates once upfront; `--yes` mode skips sudo gracefully with a warning
+- **macOS Homebrew installer** — offers to install Homebrew when `brew` is missing on macOS
+- **Node.js via nvm** — when Node.js is missing, offers to install nvm + Node.js LTS automatically
+- **Python 3 installer** — offers to install python3 via package manager when missing
+- **`safe_download()`** helper — verifies downloads are non-empty and not HTML error pages (guards against GitHub 404 / rate-limit pages being silently treated as binaries)
+- **`pkg_install()`** helper — unified cross-platform install (brew / apt / pacman / dnf)
+- **`arch_github()` / `arch_linux_x64()`** helpers — normalize `uname -m` including `aarch64` → `arm64`
+- **`trap on_error ERR`** — catches unexpected failures, shows line number and debug command
+- **`trap EXIT`** — cleans up temp files (`/tmp/chopsticks-hadolint`, `/tmp/chopsticks-marksman`)
+- **Symlink verification** — confirms `[[ -L ]]` after `ln -sf`
+- **vim-plug fallback** — if curl download fails, falls back to `git clone`; verifies file is non-empty
+- **`vim +PlugInstall` error handling** — warns on non-zero exit instead of silent continue
+- **Screen-dark notice** — informs user before each Vim fullscreen step (PlugInstall, CocInstall)
+
+### Changed
+
+- `set -e` → `set -eo pipefail` — pipeline failures now propagate correctly
+- `ask()` now reads from `/dev/tty` with a test-open check (`{ true </dev/tty; }`) — interactive prompts work under `curl | bash` and non-interactive SSH sessions fall back to "no" safely
+- Binary downloads (hadolint, marksman) use named temp files and `safe_download()` instead of bare curl
+- Arch architecture detection handles `aarch64` in addition to `arm64`
+- System tools section checks `HAS_SUDO` before running apt / pacman / dnf commands

 ## Installation
 
-### Automatic (recommended)
+### One command (recommended)
+
+```bash
+curl -fsSL https://raw.githubusercontent.com/m1ngsama/chopsticks/main/get.sh | bash
+```
+
+This bootstrap script clones the repo to `~/.vim`, then runs the full installer.
+It works correctly even when piped from curl — interactive prompts use `/dev/tty`.
+
+For non-interactive or CI environments:
+
+```bash
+curl -fsSL https://raw.githubusercontent.com/m1ngsama/chopsticks/main/get.sh | bash -s -- --yes
+```
+
+### Traditional (git clone)
 
 ```bash
 git clone https://github.com/m1ngsama/chopsticks.git ~/.vim
-cd ~/.vim
+cd ~/.vim && ./install.sh
-./install.sh
 ```
 
-The installer handles everything in sequence:
+### What the installer does
 
-1. Verifies Vim 8.0+ and detects OS / package manager
+1. **Preflight** — checks network, detects OS and package manager, verifies or installs `curl`, `git`, and `vim`
-2. Backs up any existing `~/.vimrc` with a timestamp
+2. **sudo** — authenticates once upfront; gracefully skips system packages when unavailable
-3. Symlinks `~/.vimrc → ~/.vim/.vimrc` and `~/.vim/coc-settings.json`
+3. **macOS** — offers to install Homebrew if `brew` is not found
-4. Installs vim-plug and runs `:PlugInstall`
+4. **Node.js** — offers to install via nvm if not found (falls back to vim-lsp if declined)
-5. Optionally installs system tools (ripgrep, fzf, ctags, shellcheck, hadolint, marksman)
+5. **Python** — offers to install Python 3 if missing; bootstraps pip3 if only python3 is present
-6. Optionally installs language tools (npm, pip, Go)
+6. **Symlinks** — backs up any existing `~/.vimrc` with a timestamp, then symlinks `~/.vimrc → ~/.vim/.vimrc`
-7. Optionally installs CoC language server extensions
+7. **Plugins** — installs vim-plug and runs `:PlugInstall` (with a progress notice during the black-screen period)
-8. Optionally configures tmux for seamless pane navigation
+8. **System tools** — ripgrep, fzf, ctags, shellcheck, hadolint, marksman (verified downloads)
+9. **Language tools** — npm formatters, pip formatters/linters, Go tools
+10. **CoC extensions** — all language servers in one step
+11. **tmux** — optionally appends vim-tmux-navigator bindings to `~/.tmux.conf`
 
 **Supported platforms:** macOS (Homebrew), Debian/Ubuntu (apt), Arch Linux (pacman), Fedora (dnf).
