What Does It Mean to Add Changes to a Previous Commit?

When you make changes to your code but realize that you forgot to include some files or made an error in your last commit, you can amend that commit instead of creating a new one. This is what it means to add changes to a previous commit in Git.

Modifying an existing commit can be beneficial for several reasons:

• To correct mistakes in the commit message.
• To include additional files that were overlooked.

1. Make your changes in the codebase.
2. Stage the changes using `git add `.
3. Run `git commit --amend` to modify the previous commit.
