Resources / Course / Chapter 02

Prerequisites

10 min read

What you need before starting — a Zo Computer account, basic orientation, and a one-prompt Clarion install.

What you will leave with
  • How to sign up for Zo Computer and pick a default chat model
  • Which areas of Zo you should know how to find (workspace, terminal, settings, hosting, automations)
  • How to install Clarion from the Zo Skills Hub and bootstrap it with a single chat prompt
  • How to store secrets safely and where your own work lives versus the engine code

You do not need to be a software engineer to take this course. You do need a Zo Computer account, basic comfort with files and folders, and a willingness to read a small amount of code without panicking. That is enough.

Required

1. A Zo Computer account

Sign up using Jing’s referral link (includes $10 in free AI credits):

https://zo-computer.cello.so/8dcc6g0vZVs

The free tier is enough to complete every exercise in Phase 1. You can upgrade later if you want more compute or longer-running services.

2. The ability to find these areas inside Zo

After you log in, take a minute to open each of these areas at least once. You do not need to do anything in them yet — just confirm you can find them. They are listed in the left sidebar.

AreaWhat it is for
WorkspaceYour files. Markdown notes, scripts, datasets, anything else.
TerminalA command line that runs inside your Zo.
SettingsWhere you choose your AI model and store secrets.
HostingWhere your sites and services live.
AutomationsWhere scheduled jobs are managed.

If you are missing any of these, your account may not be fully provisioned yet. Refresh the page; if it still does not appear, contact Zo support before continuing.

3. An AI model selected for chat

Open Settings → AI and pick a model. A free-tier model is fine for most reading and Q&A. When the course asks you to build or modify something, switch to a stronger coding-grade model (a Claude Sonnet or higher tier model is recommended). You can switch back and forth as needed.

4. Install Clarion (two steps, one time)

Clarion is published as a set of Zo skills. You install the bootstrap skill once, then ask Zo to run it. Two steps, both quick.

Step 1 — Install the clarion-setup skill

Open Skills in the left sidebar, switch to the Hub tab, type clarion into the search box, and click Install on Clarion Setup. It will show an “Installed” badge once it is ready.

Zo Skills Hub filtered to clarion-* skills, each showing an Installed badge.
Skills → Hub, filtered by “clarion”. You only need to click Install on Clarion Setup. Running it will install the other clarion-* skills for you.

You only need to install Clarion Setup. When you run it, it pulls in the rest of the clarion-* skill set automatically — regime check, value screener, SEC research, single-stock evaluation, thesis writing and monitoring, watchlist updates, and the living-letter helper. Everything shows up under Skills in one shot.

Step 2 — Run the setup from chat

With the skill installed, open the Zo chat and paste exactly this:

In Zo chat
>Set up Clarion.
Running the clarion-setup skill. This will: • clone the Clarion engine from github.com/jingerzz/clarion-intelligence-system • install the ai_buffett_zo Python library and dependencies • create your workspace at ~/clarion/ and write default config • register the SEC filing indexer as a background service • install the rest of the clarion-* skill set into Skills/ • run a green/red verification check at the end Idempotent — safe to re-run any time you want to refresh or repair the setup. Expect 2–5 minutes the first time, mostly waiting on the dependency install.

That is it. No curl-pipe-bash, no MCP server wiring, no manual Python install. If anything looks off later, ask Zo to verify:

In Zo chat
>Use the clarion-setup skill to verify and repair my setup.
Running diagnostics. The skill checks the repo clone, the Python install, the workspace structure, and the SEC indexer service, and reports each as green/red. It then attempts to repair any red checks. If a check still fails, it tells you exactly what to fix manually.
Manual install (fallback)
If you would rather run the setup from the terminal instead of chat:git clone https://github.com/jingerzz/clarion-intelligence-system.git ~/clarion-src cd ~/clarion-src bash scripts/bootstrap.shThe chat-driven path is recommended — the skill knows how to register Clarion with your Zo session so subsequent prompts find it automatically.

Recommended (but not required)

  • A Claude Sonnet-class coding model for any build steps later in the course. Faster and more accurate than the free tier when editing code.
  • Claude Code or Codex as optional coding assistants. Useful if you want to make deeper edits to the engine. Skippable.
  • Basic terminal comfort — knowing what cd, ls, python, and git do, and being willing to read an error message instead of closing the window.
  • A GitHub account if you want to fork the Clarion repository and make your own changes. Optional.

Not required

You will see these terms in the course. You do not need any prior experience with them to start.

  • Paid market data subscriptions
  • A production trading account
  • Prior MCP, RAG, or LLM internals knowledge
  • Prior experience deploying web apps
  • Prior Python expertise beyond reading short scripts

If any of those are familiar, the course will move quickly for you. If none of them are, the course was written for you specifically.

Accounts and access

Zo can store credentials as environment secrets. Never paste API keys directly into course files or chat messages. When the course needs a key, it will tell you where to put it inside Zo settings.

The course relies on free public data sources where possible:

  • Yahoo Finance for stock and ETF price data
  • SEC EDGAR for company filings
  • Local files and hosted services on Zo for everything you build

You will not need a Bloomberg terminal, a Refinitiv subscription, or a paid API key to complete the exercises.

Where your work lives

The setup above creates two things in your workspace:

  • ~/clarion-src/ — the Clarion engine source code (the repository contents). You do not need to touch this folder — it is owned by the installer and is updated when you re-run the setup skill.
  • ~/clarion/your workspace. Config, theses, watchlists, research notes, decision logs. This is the folder that compounds over time. The engine reads from it; your own work writes to it.

Keep the structure boring. The point is that the AI can find things later without asking. We will explain why this matters — and walk through what each subfolder is for — in Chapter 04 (Foundations 2).

When the install finishes and the verification check comes back green, you are ready for Chapter 03 — Zo as an AI Operating Environment.
