+## HPC Integration
+
+To run training on the VSC HPC (Ghent Tier 2):
+
+### Setup
+
+Run the installation script once on a login node. This sets up a virtual environment in `$VSC_DATA` with the required system modules (JAX, Flax, WandB) and lightweight dependencies.
+
+```bash
+bash scripts/hpc_install.sh
+```
+
+### Smoke Test
+Verify everything runs on a compute node:
+```bash
+python src/train.py --config configs/hpc_smoke_test.yaml
+```
+
+### Submitting Jobs
+Submit long-running experiments via the provided Slurm script:
+```bash
+sbatch scripts/hpc_train.slurm
+```
+
+### Syncing WandB
+Since compute nodes are offline, sync your WandB logs after the job finishes:
+```bash
+wandb sync runs/<run_name>/wandb
+```
