+# ID Tech Learning Center
+
+This Hugging Face dataset repository mirrors the public machine-readable corpus published by the ID Tech Learning Center at [learn.idtechwire.com](https://learn.idtechwire.com).
+
+The canonical source remains the Learning Center itself. This mirror exists to make the datasets easier to discover and consume in AI, retrieval, and model-development workflows that already use the Hugging Face ecosystem.
