+# OHIF Viewer Test Data Set
+
+The [viewer-testdata](https://github.com/OHIF/viewer-testdata) repository provides version-controlled DICOM studies used to test [OHIF Viewer](https://github.com/OHIF/Viewers) and related DICOMweb integrations. Source files live under `dcm/`; static DICOMweb output is generated with `mkdicomweb` into `dicomweb/`.
+
+Study metadata below was read from one representative `.dcm` file per directory (tags `(0010,0010)`, `(0010,0020)`, `(0020,000D)` via `dcmdump -w 192`). All instances within a directory share the same patient and study identifiers.
