 # Git Prune Local
-Script to delete local branches which are deleted in remote
+Script to delete local branches which are deleted in remote.
+
+The motivation came from day to day basis of keeping track of hugely growing project. When there are too many local branches created and then pushed to repository and after successful merging are deleted from remote, but keep hanging in your local copy.
+
+I tried to search for some solution where this can be handled when I pull code or fetch. There is also no out of the box solution, or I was lazy enough to search more than 5 links of Stackoverflow (afraid of I would find the Dead body on next page of google).
+
+Anyways, its an effort to provide a script to make sure I have peace of mind and won't do more manual work.
+
+What I believe is Automate it, If it is regular process.
