Create a Google Sheet with the required tabs: Config, Courses, Scores YYYY, and Rounds YYYY. See the README for the exact column layouts. Make sure the sheet is published (File → Share → Publish to web).

Open your Google Sheet. The Sheet ID is the long string in the URL between /d/ and the next /.Example: docs.google.com/spreadsheets/d/1YlBA...veGU/edit

Mac: Open TextEdit → Settings → "Open and Save" tab → check "Display HTML files as HTML code instead of formatted text". Then open index.html.

Windows: Right-click index.html → Open with → Notepad.

Or use any code editor (VS Code, Sublime Text, etc.)

Near the top of the file, find the line:

const SHEET_ID = '';

Paste your Sheet ID between the quotes:

const SHEET_ID = 'your-sheet-id-here';

Save the file and open it in a browser, or deploy to GitHub Pages.
