 #### Example usage:
 1. One version analysis:
 ```
-python3 main.py -w metamask/metamask-extension -v 1.11.0 -s -pm yarn-berry
+python3 main.py -w MetaMask/metamask-extension -v v11.11.0 -s -pm yarn-berry
 ```
 
 2. Differential analysis:
 ```
-python3 main.py -w metamask/metamask-extension -v 1.11.0 -vn 1.12.0 -s -d -pm yarn-berry
+python3 main.py -w MetaMask/metamask-extension -v v11.11.0 -vn v11.12.0 -s -d -pm yarn-berry
 ```
 
 Notes:
+- `-v` should be the version of GitHub release, e.g. for [this release](https://github.com/MetaMask/metamask-extension/releases/tag/v11.1.0), the value should be `v11.11.0`, not `Version 11.11.0`.
 - The `-s` flag is required for all analyses.
 - When using `-d` for differential analysis, both `-v` and `-vn` must be specified.
