+### NetCDF Engines
+
+NetCDF Explorer uses [xarray](https://xarray.dev/) to read uploaded files. Since files are streamed from MinIO into memory,
+xarray selects a backend engine that supports reading from in-memory buffers. The engine is chosen automatically at runtime
+based on the file format:
+
+| File Format | Engine | Notes |
+|-------------|--------|-------|
+| NetCDF3 (classic) | `scipy` | Handles classic and 64-bit offset NetCDF formats |
+| NetCDF4 / HDF5 | `h5netcdf` | Reads HDF5-based NetCDF4 files via `h5py` |
