### Altmetric Summary Page Widget
#
# For the Altmetric badges to work properly you need to contact support@altmetric.com 
# and give them the domain your IR is hosted on.
# If you skip this step users may not see the full details for each article
#   e.g. only the most recent tweets or likes may be shown.
