*   Commands related to a remote repository:
    
    *   `git clone git@github.com:USER-NAME/REPOSITORY-NAME.git`
        
    *   `git push` or `git push origin main` (Both accomplish the same goal in this context)
        
*   Commands related to the workflow:
    
    *   `git add .`
        
    *   `git commit -m "A message describing what you have done to make this snapshot different"`
        
*   Commands related to checking status or log history
    
    *   `git status`
        
    *   `git log`
        

The basic Git syntax is `program | action | destination`.

For example,

*   `git add .` is read as `git | add | .`, where the period represents everything in the current directory;
    
*   `git commit -m "message"` is read as `git | commit -m | "message"`; and
    
*   `git status` is read as `git | status | (no destination)`.
    

Delete commits:

`git reset --hard HEAD~1 - delete last commit`

You can also remove up to a specific commit using a commit’s hash, like so:

`git reset --hard <hash>`

To delete commits from remote, you will need to push your local changes to the remote using the [git push](https://timmousk.com/blog/git-push/?ref=hackernoon.com) command.

`git push origin HEAD --force`

Undo commit, but keep changes:

`git reset --soft HEAD~1`
