What is the difference between summary and description in GitHub Desktop?

Question

Though I don't find it annoying or anything like that but I just wanted to know how is specifying either of the summary or description different while making a commit using the desktop version on GitHub? How do I provide these two together on terminal using git commit ?

Answer 1

The summary is the first line of a commit message: it summarizes the reason for the commit (why, not what)
See "The Art of the Commit"

The rest goes into the description.

---

By convention, that first line is not supposed to be more than 50 characters:
See this template

# <type>: (If applied, this commit will...) <subject> (Max 50 char)
# |<----  Using a Maximum Of 50 Characters  ---->|


# Explain why this change is being made
# |<----   Try To Limit Each Line to a Maximum Of 72 Characters   ---->|

# Provide links or keys to any relevant tickets, articles or other resources
# Example: Github issue #23

Other Git GUIs do enfornce the same summary/description convention, like Atomio:
