# Git Commit standards
## _For better understanding & reviews_
Here im suggesting a useful way for writing better commit messages. Set your commit message template to:

download this template and save as ~/.git_commit_msg.txt
https://gist.github.com/januprasad/76bbde852fd1f943eb486de2848a0772

then run this command in your terminal 
git config --global commit.template ~/.git_commit_msg.txt
