+## Datasets
+
+Trained on 3 concatenated datasets:
+
+1. [`hemlang/Hemlock2-DPO`](https://huggingface.co/datasets/hemlang/Hemlock2-DPO) (split: `train`)
+2. [`hemlang/hemlock-formulary-SFT`](https://huggingface.co/datasets/hemlang/hemlock-formulary-SFT) (split: `train`)
+3. [`hemlang/hemlock-codex-SFT`](https://huggingface.co/datasets/hemlang/hemlock-codex-SFT) (split: `train`)
+
+## Reproduce this training run
+
+This model was trained with [Merlina](https://github.com/Schneewolf-Labs/Merlina). Save the JSON below to `data/configs/<name>.json` (or import it via the *Load Configuration* dialog) to reproduce the exact training setup. Credentials are not included — Merlina will use your own `HF_TOKEN` and `WANDB_API_KEY` from `.env` or the form.
