3. Add all the files into staging index from working directory(working copy)
   

   git add .

   OR
   

   Add specified file into the staging index

   git add fileName.html

4. add the files into the repository
   

   git commit :- add message in the opened file

   OR
   

   git commit -m "type your message to identify the commitment" :- add message without opening the file using the default editor
