+💚💜 Thank you for interest. ❤️💛
+Please make sure to check for more efficient package management. *Please prioritize checking existing issues first. I will repay with higher-quality code.*
+
+**To Reproduce**
+- [ ] I have read [README.md](https://github.com/dsdanielpark/Bard-API). Please read me.
+- [ ] I have searched for existing issues. *(Most of the issues are duplicates.)*
+- [ ] I installed the appropriate version and confirmed that the previous version was properly removed upon reinstallation. 
+- [ ] I also checked the environment (not only on a single local machine but also on Google Colab, different Google accounts, and tried resetting cookies, etc. Please make sure to attempt these steps if necessary, and test the functionality in a new virtual environment if needed.)
+
+Example
+```
+pip uninstall bardapi # and restart kernel
+pip install bardapi==0.1.29 # check proper version
+pip install -u bardapi==0.1.29 # upgrade version
+```
+
+```python
+import bardapi
+bardapi.__version__
+```
