Add

Answer 23

Add: In Git, an add is what tells your repository, “Hey, I want you to add these changes to the next version of the project!” You add files to the staging area to have them included in your next commit (see below). If you add a file and then make more changes to it, you must re-add the file to include all of your recent changes.

git add index.html
to add a specific file, indelx.thml to the staging area
git add .
to add all changed files to the staging area

Question 24

Commit

Answer 24

Commit: Once you feel your project has reached a point where it should be saved, you tell Git to commit all your files in the staging area. This means every file you have added will be updated with the changes you have made. With every commit, you create another local version of your project. Additionally, Git clears the staging area each time you do a commit.
git commit -m ‘Name to identify commit goes here’
