# v0.4.1 Installation Notes

Date: 2026-07-06

## Goal

Restore clear one-command installation instructions for Codex CLI, Claude Code, and other mainstream AI coding platforms.

## Changes

- Added `docs/installation.md` with one-command and manual installation paths.
- Updated README and README_EN Quick Start sections.
- Cleaned installer output to plain ASCII so it renders correctly in terminals.
- Updated `VERSION` to `0.4.1-preview`.

## Result

New users can install paper-skill across the major supported AI platforms without guessing the target directory or invocation command.
