LinkedIn is a wonderful social network that connects people of different field, levels and help them to achieve their occupational goals.
It is designed as a professional network for business people, job seekers, organizations and so on.
But for a new user it is quite tough to understand its functionalities and to utilize it well.
I would suggest you to try LinkedIn Scraper, it will help you to add information, scrap valuable data from your LinkedIn connections quickly and much more.

Go to the linkedin web-site on the internet, log in. Click the picture of yourself at the very top right on the linked in page, then once your main picture appears click the "Edit Profile" button underneath it.
