+## Setup
+
+### Linux
+
+```bash
+# Prerequisites: Rust toolchain, iptables
+./scripts/setup-linux.sh
+```
+
+Creates a `zerogravity-ls` system user for UID-scoped iptables isolation, installs a systemd user service, and builds the release binary.
+
+```bash
+# Start the service
+systemctl --user enable --now zerogravity
+
+# Or use the daemon manager
+zg start
+```
+
+### macOS
+
+```bash
+# Prerequisites: Rust toolchain
+./scripts/setup-macos.sh
+```
+
+Installs a launchd plist for automatic startup. No UID isolation — runs in headless/HTTPS_PROXY mode only.
+
+```bash
+# Start the service
+launchctl load ~/Library/LaunchAgents/com.zerogravity.proxy.plist
+
+# Or use the daemon manager
+zg start
+```
+
+### Windows
+
+```powershell
+# Prerequisites: Rust toolchain
+# Run as Administrator
+powershell -ExecutionPolicy Bypass -File scripts\setup-windows.ps1
+```
+
+Creates config directories, builds the release binary, and installs a scheduled task for automatic startup at logon.
+
+```powershell
+# Start now
+schtasks /run /tn "ZeroGravity Proxy"
+
+# Or manually
+.\target\release\zerogravity.exe
