How to add a new group member

[pepaaran]

To create a new profile in the "People" page for Firstname Lastname, follow these steps:

1. Create a new directory in the repository called ./content/authors/firstname-lastname. This naming ensures that paper and blogpost authors are recognized.
2. In this folder, create a _index.md file following the structure of this example. Fill it out with the information from the new member, and make sure to set the user_groups YAML argument to the appropriate group (see a list of available groups here).
3. Add a picture named avatar.png/jpg to that same folder. Make sure when you render the website that the face isn't cropped and modify the image accordingly.
4. Check if everything looks okay with serve_site().
