HOW-TO: create a Drupal views block to display the current node content
In views section, for an existing view or newly created one, do the following:
- Click "Add" > "Block"
- Fill in whatever you normally would do in views (this is beyond the scope of this tutorial)
- Under "Contextual Filters" > click "Add" > "Content: Nid" > "Provide default value" > "Content ID from URL"
And that's that...
