Edit the front page

To the right of the welcome message is an image block. If you haven't added any images, yet, this space will be empty. (See add images)
Below welcome message and images is a row of three blocks. These blocks are only visible when content is available for the respective content types.

Click on the Edit tab above the welcome message to have a look at the blocks. At the top of the overlay you can edit the welcome message if you want. At the bottom you can select which small blocks to show on the front page. The default is for Page, Biblio, and Taxon description.
