• git add . --- move all files in current dir to the stage
• git add --all --- move all files in current dir to the stage
• git add -p yourfile.html --- allow you to CHOOSE what changes you want to commit in this file. (example -> if you added 2 lines of code git will offer you to commit changes line by line. You can choose to save (commit) first added line but not second. Very convinient feature!.)
• git rm --cached filename --- remove file from stage area

• git commit -m --- commit changes from staging with a message
• git commit -a --- commit without git add for TRACKED files
• git remote -v --- shows which github repos are connected with ur local repo
• git remote add origin https://github.com/Dzentsetsu/Tips.git --- creates a handle in your local repo with alias ORIGIN to this "https://github.com/Dzentsetsu/Tips.git" repo (now you can fetch from it and push to it)
• git remote remove alias --- removes a handle to github repo (this is used when for example you have 2 repos where you commit ur local files to and now you do not want to use one of them anymore,so you can delete a handle to it)
• git push -u origin my_branch --- type this if it is the first time that you push that branch in just created repo.
• git clone <remote_URL> --- clone project.
• git commit -a --allow-empty-message -m ' ' --- let you make a commit with no message. Pretty usefull when working alone

If you want fast check any repo, write 1s after letter b in url (github.com/blablabla ---> github1s.com/blablabla). It will open repo in vscode in the browser!! 😎
