This exercise is not obligatory if you are not to work with the Staff portal. You are of course welcome to do it anyway - it's quick!

Go to the page If you get ill: https://staff-drupalkurs.ki.se/if-you-get-ill
Click on the pen and then on Add local content.
Click on Group members and locate your department or unit, depending on your choice.
Fill in a suitable heading under Administrative title. You do not need to write that it is a local extension addressed to the department, that will appear. Therefore, write something else for example "Contact person" Since the context is clear you can use general headings for specific local extensions.
Enter your own KI ID under the content curator.
Click Add block and select text / image.
Fill in a text. One sentence is enough. You can however use many blocks for rich content if necessary.
Save. When the page opens, you might not be able to see the extension even though you have selected a group you belong to. This is because the practice page does not link to IDAC in the same way as the production environment. This will work once you are doing real work on the real staff portal.
