How can I add and edit page content?
Adding page content is simply done by a drag and drop move of the block you want to add. The possibilities are:
      • Text
      • Single picture
      • Picture gallery
      • Attachments
      • Embedding (advanced)
Just drag the block to the desired position on the page and edit the block with your own content. You're always free the alter the position of the blocks later on with a simple drag and drop move, so don't worry if you want to change the position of the blocks. 
Note that there is a possibility to work with a column structure on your page, where column width can change per created section.

Watch the movie to see a demonstration of how it's done (voice-over is in Dutch).
