Installation (Developer / Local)

These steps are for loading the extension locally during development.

1. Clone or copy the extension source into a directory on your machine.
2. Open Chrome and go to chrome://extensions/.
3. Enable Developer mode (toggle in the top-right).
4. Click Load unpacked, then select the extension directory (the folder containing manifest.json).
5. The extension should appear in the toolbar. If the icon is hidden, click the puzzle icon and pin it for easy access.

Usage

1. Open any LeetCode problem page (for example: https://leetcode.com/problems/two-sum/).
2. Click the extension icon (it uses an icon-only button) to open the hints panel.
3. Use the provided buttons inside the panel to cycle through hint levels.
4. Hints are stored in the extension or injected from the page (depends on your implementation). No external calls are required unless you explicitly add a server integration.

Privacy & Data

• By default the extension does not send any problem data or user data to external servers.
• If you add a server-side feature (for syncing hints, analytics, etc.), clearly document what data is sent and provide an opt-in.

Troubleshooting

• Panel not showing: Make sure the content script matches pattern includes the exact URL format of LeetCode problems.
• Styles conflict: Increase specificity or wrap the panel in a unique root node (e.g., #lc-hints-root) to avoid overriding site CSS.
• Permissions error: Verify manifest_version is 3 and your host_permissions include the LeetCode domain.
