Description of the change

I would like to add links to 4 videos published on YouTube about metadata / COVID-19 HGI data dictionary made as part of ELIXIR CONVERGE WP7 which describe metadata that is relevant for FEGA. Video links are:

• https://youtu.be/U6ilhM-XOhU
• https://youtu.be/0anBkJbF7XY
• https://youtu.be/AInMx8xj_Lk
• https://youtu.be/josXa1CydxA

Reason for the change

We want to be able to share more broadly these outputs from ELIXIR CONVERGE WP7 , Task 7.3, and help groups setting up FEGA nodes to understand the data model. Also linked to training WP2.
