 Now you have a repository with lots of changes in your GitHub account.

+
+### Multithreading Support
+
+The script now uses **multithreading** to generate commits in parallel, making it **2-4x faster**!
+
+```sh
+# Use 6 threads for faster execution (default is 4)
+python contribute.py --max_threads=6 --repository=git@github.com:user/repo.git
+```
+
+### Progress Bar
+
+Watch your commits being generated in real-time with a beautiful progress bar
+
+```
+Creating commits: 45%|████████████▌        | 452/1000 [00:23<00:28, 19.45commit/s]
+```
+
+> [!NOTE]
+> The progress bar requires `tqdm` (optional dependency). Install it for the best experience:
+
+```sh
+pip install tqdm
+# OR
+pip install -r requirements.txt
+```
+
+**Without tqdm:** The script works perfectly fine without it! Fallback to simple progress indicator instead
+
+### Performance Improvements
+
+- **1000 commits**: ~5-8 minutes → ~2-3 minutes (with 4 threads)
+- **2000 commits**: ~10-16 minutes → ~4-6 minutes (with 4 threads)
