Blocks are places provided by the theme.
Through structure you can set the configuration
Each theme has his own blocks. If you are not happy with these blocks, Display Suite en Panels can make more..
We see 2 tabs. The current blocks and the blocks you can fill in yourself.
You can add content to a block:
Give the block a place..
You can set filters. Eg show them only on the home page...

en kies uit de bibliotheek.
