Here's a sample repository created using LeetCode Synchronizer: leetcode-synchronizer-sample

• Fully automated collection of all your latest accepted submissions with minimal effort setup
• Single commit for each submission stamped with the original submission date for building rich and accurate contributions graph
• Automated git pushes to the remote repository with every action triggers
• Auto-generate README.md based on retrieved submissions
