First do a wget of full website.

wget -e robots=off -U ‘Mozilla/5.0 (X11; Linux x86_64; rv:30.0) Gecko/20100101 Firefox/30.0’ –limit-rate=423k –recursive  –no-clobber  –page-requisites  –convert-links  –restrict-file-names=windows  –domains -o run1.log –no-check-certificate

Make a (local) git project inside the freshly generated folder:

git init

You’ll get “Initialized empty Git repository in ….”
One can check status using this command
git status
Now you can add the files:

git add *

Next you can commit the changes

git commit -m “added initial files to the repo”.

Later one can rerun the wget command and do a new “git status” to see changes. If so do git add and/or git commit.

Using a visual it GUI you can track changes.
