+# Linux App
+
+## Overview
+
+OpenClaw's Gateway operates on Linux systems, with Node.js as the preferred runtime environment. Bun is not recommended for the Gateway (WhatsApp/Telegram bugs).
+
+## Quick Start for VPS Users
+
+The beginner pathway involves four primary steps:
+
+1. Installing Node 22 or later
+2. Installing the OpenClaw package globally via npm
+3. Running the onboard command with daemon installation
+4. Establishing an SSH tunnel to access the interface locally
+
+## Installation Options
+
+Multiple installation approaches are available:
+
+- Standard setup procedures
+- Experimental Bun support
+- Nix package manager integration
+- Containerized Docker deployment
+
+## Service Management
+
+OpenClaw implements systemd user services by default, though system-wide services suit shared or persistent server environments. The installation process offers three command variations for establishing the Gateway service, along with diagnostic and repair capabilities through the doctor command.
+
+### Gateway service install options
+
+- `openclaw onboard --install-daemon`
+- `openclaw gateway install`
+- `openclaw configure` (select Gateway service when prompted)
+
+Use `openclaw doctor` to diagnose or repair installations.
+
+## Configuration
+
+A minimal systemd service unit requires specifying the Gateway startup command with port configuration, restart policies, and user-level enablement through systemctl commands.
