Proper git messages - Rules and examples

##The seven rules of a great git commit message

1. Separate subject from body with a blank line
2. Limit the subject line to 50 characters
3. Capitalize the subject line
4. Do not end the subject line with a period
5. Use the imperative mood in the subject line
6. Wrap the body at 72 characters
7. Use the body to explain what and why vs. how

##Other general advce:

1. Don't vary wildly in length and form
2. teams should first agree on a commit message convention that defines style(syntax, grammar, punctuation), content, metadata(issue tracking IDs, pull request numbers) ​
