# Start in three steps

1. Download the ZIP.
2. Extract it (double-click on Mac; Extract All on Windows).
3. Open OPEN-ME.html in your browser. Run your first exercise there.

You do not need Python or an assistant for the first browser exercise. The following instructions are optional, for the next coding lesson.

# Download and run — plain-language instructions

1. Select Download Launch Kit on the CT preview page. Save the ZIP file somewhere you can find it.
2. Extract the ZIP. On Windows, right-click and choose Extract All. On macOS, double-click it.
3. Open the extracted ct-ai-developer-launch-kit folder. Start with START-HERE.md; Markdown files are readable in a text editor.
4. Check Python. Open Terminal on macOS or PowerShell on Windows. Enter `python3 --version` on macOS or `py --version` on Windows. You need Python 3.10 or later. If unavailable, use https://www.python.org/downloads/ and its platform instructions, then reopen the terminal.
5. Open a terminal in the extracted folder. You can type `cd `, followed by the folder path in quotes. Example: `cd "path/to/ct-ai-developer-launch-kit"` — replace the example path with your actual folder.
6. Run the example: macOS `python3 workflow_demo.py`; Windows `py workflow_demo.py`.
7. Run the checks: macOS `python3 -m unittest test_workflow.py`; Windows `py -m unittest test_workflow.py`.
8. Expect a fictional research report and five passing tests. No network connection or trading account is used by the example.
9. To use an assistant, read ASSISTANT-SETUP.md. Share the project guide before asking it to edit code.

If you see File not found, check the extracted folder and your current terminal directory. If Python is not recognized, revisit the official installation instructions. If a test fails after your changes, inspect the named test rather than deleting it.

Download contents: beginner guide, shared project guide, assistant setup instructions, this setup checklist, an offline Python example, fictional JSON data, and tests. This is the foundation edition, not the complete planned curriculum.
