You don't want to clone again.  Use "git pull".

git status  -- to see what files are (not) under git control

git diff  --  to see what *you* changed but did not yet commit

git whatchanged  -- to see change history of your current source tree

git whatchanged origin/master  -- for changes you may not have "pull"ed
