# Toolkit Contributors and Users

Building the Toolkit is a global, community effort and the fruits of that work are used even more widely. The below map shows the location of the developers, contributors and users of the Toolkit.

The location of the lead institutions are shown in red, contributors are shown in blue and users in yellow. If you fall into any of these categories and are missing from the map let us know so we can add you.

## Papers that acknowledge, cite and/or extend the Toolkit

The graph below show the accumulated citations to the Toolkit over time. The blue curve shows the total citations and acknowledgements, the red curve tracks the total number of papers that have contributed software or data to the Toolkit.
