+## Dataset Structure
+
+When you run the code from [ines-lang/pde-solver](https://github.com/ines-lang/pde-solver), it automatically generates a directory structure based on the **selected PDE** and **initial condition (IC)**.
+
+This folder structure matches the format in which this dataset is organized and shared here.
+
+### Example structure for a 1D PDE dataset:
+
+
+1D/
+├── pde/
+│   └── ic/
+│       ├── dataset.h5
+│       ├── metadata.json
+│       └── plots/
+│           └── seed_i.png  # for 1D
+
+
+### File descriptions:
+- **`dataset.h5`**: Contains the full dataset with the generated PDE solution data.
+- **`metadata.json`**: Describes the PDE type, initial conditions, and solver parameters.
+- **`plots/`**: Contains sample visualizations for each generated seed.

+You can extend this structure to other PDEs and dimensions (e.g., `2D/`, `3D/`) following the same hierarchy.
