+### Use PostgresSQL w/ Orthanc
+
+Orthanc can handle a large amount of data and requests, but if you find that
+requests start to slow as you add more and more studies, you may want to
+configure your Orthanc instance to use PostgresSQL. Instructions on how to do
+that can be found in the

+"PostgreSQL and Orthanc inside Docker"
