+# CarbonOps Datasets
+
+Public datasets for **carbon-aware DevOps**:
+- Normalised **grid carbon-intensity time series** by region.
+- Sample **CI/CD telemetry** (duration, artifacts) to estimate grams CO₂e per build.
+
+> Status: pre-alpha. Not for real-time operational decisions.
+
+## Schema (grid-intensity)
+| field                     | type     | description                                   |
