-## Claude + Sidepit: two terminals
+## Get started
 
-**Step 1 — install the cockpit.** Python 3.10 or newer. Nothing compiles: every piece arrives as a prebuilt
-wheel on Linux, macOS (Apple Silicon and Intel) and Windows. Pick your machine
-and follow the steps top to bottom.
+Choose the [website](#use-the-website) or the [command-line cockpit](#use-the-command-line-cockpit).
+
+You can also start by asking your agent to onboard you. Give it the
+[onboarding playbook](skills/sidepit-onboarding/SKILL.md) and say:
+
+> Read https://github.com/sidepit/Public-API/blob/main/skills/sidepit-onboarding/SKILL.md
+> and onboard me. Ask whether I prefer the website or the command line.
+
+The agent should guide your chosen path. A terminal agent can guide you through
+the website just as a browser assistant can.
+
+### Use the website
+
+Start with the [Sidepit user docs](https://docs.sidepit.com) and open
+[the trading app](https://app.sidepit.com). Follow the docs for wallet setup,
+funding and authorizing an agent. This path needs no cockpit installation or
+repository clone.
+
+For help in your browser, open [Claude](https://claude.ai) or
+[ChatGPT](https://chatgpt.com) and paste the onboarding prompt above, adding
+"Use the website." Keep the assistant beside the trading app as you follow the
+guide. Agents can read the docs through [llms.txt](https://docs.sidepit.com/llms.txt)
+and its linked Markdown pages.
