This is a process through which, we request Git, to put files into a commit? This is where the staging environment or index comes in handy. When we make changes to the repo, Git notices that a file has changed but will not do anything with it (like adding it in a commit). To add a file to a commit, we need to add it to the staging environment. To do this, we can use the Git add command. Once we have used the Git, add the command to add all the files we want to the staging environment, we can then request Git to package them into a commit using the Git commit command.
