Title and description.
Now it's time to give a title to your "Realisation". Note that all achievements must have a different title.
Then you can add a description to your achievement. You can do what you want in this section with the "WYSIWIG" console. You can add links, buttons, images, videos, PDF documents ... the list is long! And you can make a nice layout using title sizes, images, ect.
Once completed, click on the "Send" button at the bottom of the page.
