Commit

You might say

Save the code changes I have now—I don't want things to get messy and lose this working version.

Save one meaningful set of changes in the project historyA commit records the selected changes with an author, time, and message. It should describe one understandable step so someone can review or restore it later. Creating a commit is local; it does not send anything to a remote until push runs.

Commit is to create a named version record for this change. It is saved locally first; in order for GitHub to receive it, it needs to be pushed.

Quick checkChoose the best answer

git status shows changes in index.html and .env, but this commit should contain only the homepage navigation. What is safer?

Stage only index.html, inspect the staged diff, then commit with “Fix homepage navigation”Run git add . and commit both files, then clean it up laterCommit .env now and delete it from the latest version before pushing

You can say this to an AI Agent

Inspect git status and the diff first. Commit only the homepage navigation changes and exclude .env. Write a message that says what was completed. After committing, give me the commit hash and confirm that nothing has been pushed yet.
