 ## About
 
-PyGMT is a library for processing geospatial and geophysical data and making publication-quality
-maps and figures. It provides a Pythonic interface for the
-[Generic Mapping Tools (GMT)](https://github.com/GenericMappingTools/gmt), a command-line program
-widely used across the Earth, Ocean, and Planetary sciences and beyond.

 ## Project goals
 
 - Make GMT more accessible to new users.
 - Build a Pythonic API for GMT.
 - Interface with the GMT C API directly using ctypes (no system calls).
 - Support for rich display in the Jupyter notebook.
-- Integration with the [scientific Python ecosystem](https://scientific-python.org/): `numpy.ndarray` or
-  `pandas.DataFrame` for data tables, `xarray.DataArray` for grids, and `geopandas.GeoDataFrame` for geographical data.
