-# Basemap
+# basemap
 
-Plot on map projections (with coastlines and political boundaries)
-using matplotlib.
+Plot on map projections (with coastlines and political boundaries) using
+[`matplotlib`].
 
-## Requirements
-
-Basic requirements are the following:
-
-* Python 2.6 (or higher)
-* [matplotlib](https://github.com/matplotlib/matplotlib)
-* [numpy](https://github.com/numpy/numpy)
-* [pyproj](https://github.com/pyproj4/pyproj)
-* [pyshp](https://github.com/GeospatialPython/pyshp)
+## Installation
 
-Optional requirements include:
+Precompiled binary wheels for Windows, GNU/Linux and MacOS are available
+on PyPI and can be installed with [`pip`]:
+```sh
+python -m pip install basemap
+```
 
-* [OWSLib](https://github.com/geopython/OWSLib). It is needed for the
-  method `Basemap.wmsimage`.
+For specific details on how to install [`basemap`] through [`conda`] or
+from source, please refer to the [`basemap` installation instructions]
+in the documentation.
 
-* [Pillow](https://github.com/python-pillow/Pillow). It is needed for
-  the methods `Basemap.bluemarble`, `Basemap.etopo`,
-  `Basemap.shadedrelief` and `Basemap.warpimage`.
+## Requirements
 
-## Installation
+This package depends on [`basemap-data`] with the basic [`basemap`]
+data assets supporting the essential functionality.
 
-The `basemap-data` and `basemap-data-hires` packages are available in
-PyPI and can be installed with [`pip`](https://pip.pypa.io/):
+This package depends optionally on [`basemap-data-hires`] with
+the high-resolution data assets, which can be installed manually
+with [`pip`]:
 ```sh
-python -m pip install basemap-data
 python -m pip install basemap-data-hires
 ```
 
-Precompiled `basemap` binary wheels for Windows and GNU/Linux
-(architectures x86 and x64, Python 2.7 and 3.5+) as well as for MacOS
-(architectures x64 and arm64, Python 3.9+) are also available in PyPI:
-```sh
-python -m pip install basemap
-```
-
-Otherwise, you will need to install `basemap` from its source hosted
-on GitHub as indicated in the following steps:
-
-1. Install pre-requisite Python modules:
-   - [cython](https://github.com/cython/cython)
-   - [numpy](https://github.com/numpy/numpy)
-
-2. Download the `basemap` source code and move to the `packages/basemap`
-   folder:
-   ```sh
-   git clone --depth 1 https://github.com/matplotlib/basemap.git
-   cd basemap/packages/basemap
-   ```
-
-3. Build the [GEOS](https://github.com/libgeos/geos) library. You may
-   use the helper provided in `utils`, (please note that you need
-   [`CMake`](https://cmake.org/) and a working C compiler in advance):
-   ```sh
-   export GEOS_DIR=<your desired location>
-   python -c "import utils; utils.GeosLibrary('3.6.5').build(installdir='${GEOS_DIR}')"
-   ```
-   or you can link directly to the system library if it is already
-   installed. `GEOS_DIR` must point to the GEOS installation prefix;
-   e.g. if `libgeos_c.so` is located in `/usr/lib` and `geos_c.h` is
-   located in `/usr/include`, then you must set `GEOS_DIR` to `/usr`.
-
-4. Build and install the `basemap` binary wheel:
-   ```sh
-   python -m pip install .
-   ```
-   On Linux, if your Python was installed through a package management
-   system, make sure that you have the Python header `Python.h` required
-   to build Cython extensions (e.g. on Debian-like systems, you should
-   have the package `python-dev` installed).
-
-5. Check that the package was installed correctly by executing:
-   ```sh
-   python -c "from mpl_toolkits.basemap import Basemap"
-   ```
+This package depends optionally on [`OWSLib`] for the `Basemap` method
+`Basemap.wmsimage`.

-# basemap
-
-Plot on map projections (with coastlines and political boundaries) using
-[`matplotlib`].
-
-This package depends on the support package [`basemap-data`] with the
-basic [`basemap`] data assets, and optionally on the support package
-[`basemap-data-hires`] with high-resolution data assets.
-
-## Installation
-
-Precompiled binary wheels for Windows and GNU/Linux are available in
-PyPI (architectures x86 and x64, Python 2.7 and 3.5+) and can be
-installed with [`pip`]:
-```sh
-python -m pip install basemap
-```
-
-If you need to install from source, please visit the
-[GitHub repository](https://github.com/matplotlib/basemap) for a
-step-by-step description.
-
-## License
-
-The library is licensed under the terms of the [MIT] license (see
-[`LICENSE`]). The GEOS dynamic library bundled with the package wheels
-is provided under the terms of the [LGPLv2.1] license as given in
