broken link for sharing groups

I found a broken link for the sharing groups section
at: 
https://github.com/MISP/misp-book/tree/master/sharing
There is an article about sharing groups in [here](https://github.com/MISP/misp-book/blob/master/sharing/using-the-system/#create-and-manage-sharing-groups) <- this link is broken
should point to:
https://github.com/MISP/misp-book/blob/master/using-the-system/#create-and-manage-sharing-groups

The same error was found at CIRCL website:
Where the link there 
https://www.circl.lu/doc/misp/sharing/using-the-system#create-and-manage-sharing-groups
should be changed in
https://www.circl.lu/doc/misp/using-the-system/#create-and-manage-sharing-groups
