          Hello, lovely contributors! As Hacktoberfest 2024 and the crisp Fall breeze refreshes us, we wanted to make the contribution process extra fun. Check our live leaderboard below to see who our top contributors are this year in real-time. Not only does this recognize everyone's efforts, it also brings an amplified competitive vibe with each contribution.

          ### 🌟 **Current Rankings:**

          | Rank | Contributor | Points | PRs |
          |------|-------------|--------|-----|
          ${leaderboardData.map(entry => `| ${entry.rank} | @${entry.username} | ${entry.points} | ${entry.prs} |`).join('\n')}

          ### 📜 How It Works:
          The top 10 contributors with the most points will snag custom swag with this year's exclusive TBD x Hacktoberfest 2024 design. To earn your place in the leaderboard, we have created a points system that is explained below. As you complete a task by successfully merging a PR, you will automatically be granted a certain # of points.

          #### 💯 Point System
          | Weight | Points Awarded | Description |
          |---------|-------------|-------------|
          | 🐭 **Small** | 5 points | For smaller tasks that take limited time to complete and/or don't require any product knowledge. |
          | 🐰 **Medium** | 10 points | For average tasks that take additional time to complete and/or require some product knowledge. |
          | 🐂 **Large** | 15 points | For heavy tasks that takes lots of time to complete and/or possibly require deep product knowledge. |

          #### 🎁 Rewards
          - Made it to the **top 10**? Our Top 10 Contributors with the most points will be awarded TBD x Hacktoberfest 2024 swag from our [TBD shop](https://www.tbd.shop/s/shop). Keep an eye on your progress to make sure you're one step ahead!
          - Among our **top 3**? Our Top 3 Superstars earn very limited, customized TBD x Hacktoberfest 2024 swag with your name on it. Stay tuned for the reveal!

          ### FAQ
          - **Frequency of Updates:** The leaderboard will be updated every 1 hour.
          - **Criteria:** Rankings are based on how many points you earn across all participating TBD repos. To ensure your PRs are successfully merged:
            - Ensure your contributions are aligned with our [project's CoC](https://developer.tbd.website/open-source/code-of-conduct).
            - Refer to each participating repo's [Contributing Guide](https://github.com/TBD54566975/developer.tbd.website/blob/main/CONTRIBUTING.md).
