The homepage includes a unique content builder specific to this page. There are three block types - Image and Copy, Programs Block, and Related Three.
Add as many of each block as needed, however the Programs Block should only be placed once - this block will display the 5 most recent Programs entries. To control the content of each of those entries go to Entries > Programs and edit an entry.
