======================================
+I installed shapely in a conda environment using pip. Why doesn't it work?
+--------------------------------------------------------------------------
+
+Shapely versions < 2.0 load a GEOS shared library using ctypes. It's not uncommon for users to have
+multiple copies of GEOS libs on their system. Loading the correct one is complicated and shapely has
+a number of platform-dependent GEOS library loading bugs. The project has particularly poor support
+for finding the correct GEOS library for a shapely package installed from PyPI *into* a conda
+environment. We recommend that conda users always get shapely from conda-forge.

Are there references for the algorithms used by shapely?
