-This is the project’s third open access data release which consists of
-images of 783 neonatal subjects (886 datasets). The imaging data includes structural imaging,
-structural connectivity data (diffusion MRI) and functional connectivity
-data (resting-state fMRI). This data release comes with minimal accompanying
-metadata: sex, age at birth, age at scan, birthweight, head circumference
-and radiology score. More specific information about the available data
-can be found in the [data organisation notes](organisation.html). 
 
+## Feedback
 We invite colleagues in the field to explore and
