+# Installer Internals
+
+OpenClaw provides three installer scripts from `openclaw.ai`:
+
+* **install.sh** — Primary installer supporting macOS, Linux, and WSL
+* **install-cli.sh** — Non-root alternative that bundles Node runtime
+* **install.ps1** — Windows PowerShell installer
+
+## install.sh Overview
+
+The recommended installer performs several key functions:
+
+1. Detects the operating system
+2. Ensures Node.js version 22 or higher is available
+3. Offers two installation methods:
+   - `npm install -g openclaw@latest` (default)
+   - Git-based source checkout with wrapper script
+
+The script addresses common Linux permission issues by redirecting npm's global prefix to `~/.npm-global` when necessary, then updates PATH variables in shell configuration files.
+
+Additionally, it mitigates `sharp` native install gotchas by defaulting `SHARP_IGNORE_GLOBAL_LIBVIPS=1` to avoid system library conflicts. Users needing different behavior can override this with `SHARP_IGNORE_GLOBAL_LIBVIPS=0`.
+
+When run inside an existing OpenClaw checkout, the installer prompts whether to update locally or migrate to global npm installation.
+
+## install-cli.sh
+
+This variant installs OpenClaw to a dedicated prefix (typically `~/.openclaw`) alongside a self-contained Node runtime, eliminating system-level dependencies.
+
+## install.ps1
+
+The Windows PowerShell version requires Node.js 22+ and supports both npm and git installation methods. Common issues include missing Git for Windows and PATH configuration problems with npm's global bin folder.
