 DeepDISC Configs
 ========================================================================================
 
+DeepDISC utilizes Detectron2 configs to build models and data loaders.  Refer to the Detectron2 docs for details on the config parameters.
+In general, DeepDISC will use the default config values provided by projects under Detectron2.  However, some parameters should be changed by the user.
+Here, we list some parameters that users may want to change.  Be aware that changes will be dependent on your use case and data, and this is not an all-encompaassing list.
