+# Gradient Engineer — 60‑Second Linux Analysis (Nix + LLM)
+
+Run the classic [“60‑second Linux Performance Analysis”](https://netflixtechblog.com/linux-performance-analysis-in-60-000-milliseconds-accc10403c55) checklist in one command. A portable Nix toolbox is downloaded on the fly, diagnostics run in parallel with a simple TUI, and an optional AI summary is shown at the end.
+
+- One command to run it all
+- Fast and portable
+- No Docker, no system‑wide installs
+- Optional AI summary
+
+## Quick start
+
+```bash
+# Any provider works; set one of these env vars to enable AI summary
+export ANTHROPIC_API_KEY="<your Anthropic API key>"   # Anthropic
+export OPENAI_API_KEY="<your OpenAI API key>"         # OpenAI
+export OPENROUTER_API_KEY="<your OpenRouter API key>" # OpenRouter
+
+curl -fsSL https://gradient.engineer/60-second-linux.sh | sh
+```
+
+Notes:
+
+- If no key is set, diagnostics still run; only the AI summary is skipped.
+- TUI controls: Tab toggles details; q / Esc / Ctrl+C quits.
+
+## Build from source
+
+```bash
+cd app
+go build -o gradient-engineer-go
+./gradient-engineer-go
+```
+
+## Advanced
+
+- You can override the API base URL via `OPENAI_BASE_URL` (for OpenAI/OpenRouter) if needed.
