Commit Message Guidelines

Short (72 chars or less) summary

More detailed explanatory text. Wrap it to 72 characters. The blank
line separating the summary from the body is critical (unless you omit
the body entirely).

Write your commit message in the imperative: "Fix bug" and not "Fixed
bug" or "Fixes bug." This convention matches up with commit messages

AGILE ESTIMATING AND PLANNING

Mike Cohn

CHAPTER 1. The Purpose of Planning

Plans help to guide investment decisions (this project is worth to begin?), know who needs to be available to work on a project during a given period and know if a project is on track.

You can’t perform that action at this time.
