+# OpenMHC BRITS
+
+Paper-faithful checkpoint for the MyHeartCounts NeurIPS 2026 benchmark.
+Window: daily (1440 minute), 19 sensor channels.
+
+Wrapper around a PyPOTS-backed imputer fine-tuned on the MyHeartCounts imputation training split. Reconstructs masked daily sensor windows across 19 channels.
+
+## Usage
+
+```python
+from openmhc.imputers import BRITSImputer
+import openmhc
+
+imp = BRITSImputer.from_release("hf://MyHeartCounts/openmhc-brits-imp")
+results = openmhc.evaluate_imputation(imp, version="xs")
+print(results.summary())
+```
+
+Requires the matching optional extra: `pip install 'openmhc[pypots,hf]'`.
+
+Pin a specific revision with the `@` suffix once tags are published:
+
+```python
+BRITSImputer.from_release("hf://MyHeartCounts/openmhc-brits-imp@v1.0")
+```
+
