+PROJ Service Providers
+*****************************************************************************
+
+PROJ is developed and supported by a rich ecosystem of businesses and
+individuals around the world.
+
+In this page we provide a list of service providers who
+can assist you in getting the best out of your PROJ investment.
+Their services can range from training and technical support to help you
+get started, all the way to specialized development and support services
+to advance the software and support your organization's mission-critical
+applications.
+
+
+.. note::
+
+    This list is non-exhaustive, and there are quite likely other service
+    providers in your region of the world who are not listed here.
+    If you think your organization should be listed here, please submit a
+    pull request to add it to this page.

+Core Contributors
+-----------------
+
+Core Contributor organizations have PROJ Committers and/or PSC members
+as part of their team and as such they are the closest to the core development
+of the software and are usually the best to go to for support.
+
+They are close enough to the architecture to know what is possible, and to
+ensure that any improvement to be made to PROJ gets done in the right
+way and will be included in future releases of the software.
+
+They wrote the software that you use, so you can trust them to help you get
+the most out of it.
