+### Example Encoded Archival Description (EAD) Documents and MARC Records
+
+Within this repository, members of the Metadata Standards Sub-Team shall track
+examples of [EAD Documents](https://www.loc.gov/ead/) and [MARCXML records](https://www.loc.gov/standards/marcxml/) which shall be used for testing importation and the 
+extraction of metadata within ArchivesSpace.
+
+This repository is structured with two directories at the root path, one for the
+EADs, and one for the MARC record examples. Within each of these, each contain a
+ collection of Documents or records from a participating institution or 
+ organization.
