+# Short Description
+
+Based on the compressible Euler equations, this dataset contains trajectories starting from multiple curved Riemann problems.
+
+# Dimensions
+
+The assembled NetCDF file has a **single** variable called *data* with dimensionality
+  - 10000 (number of trajectories)
+  - 21 (time steps)
+  - 4 (density, horizontal velocity, vertical velocity, pressure)
+  - 128 (x-dim)
+  - 128 (y-dim)
+
+# Download & Assembly
+
+The dataset can be downloaded, e.g., via `huggingface-cli download`.
+
+After download, the chunked data can be assembled into a single NetCDF file using the provided `assemble_data.py` script.
+Use it as follows:
+```bash
+python assemble_data.py --input_dir . --output_file CE-CRP.nc
+```
