Essential note when cloning into Angular repository

1) First change - Whenever cloning into directory there are chances of some users using "sudo" without knowing what it does exactly and what's the purpose of using sudo, leading them into a confusion and this lead to changes in git config and permission issues of which users may not be able to figure out at one spot.
2)  Second Change- There are chances of version unstability  issues in node which at times causes npm error and warnings while installing packages, I too had undergone some issues with node version conflicts at times, users who are not aware of this will be benefited with a Note prior.
