 **Note 2** we are not planning to bind any function not under MIT/LGLP licence since it would make the whole package not LGPL. If you plan to bind something dependent on CGAL/Triangle/TetGen, don't do it.

 !!! warning
     The igl python binding are in development, consider this a **beta** version.
 
 [libigl](https://libigl.github.io) is a simple C++ geometry processing library. We have a wide functionality including construction of sparse discrete differential geometry operators and finite-elements matrices such as the cotangent Laplacian and diagonalized mass matrix, simple facet, and edge-based topology data structures.
 
-All these functionalities are now available through python and can be easily installed with conda:
+All these functionalities are now available through python and can be easily installed with pip:
 ```bash
-conda install -c conda-forge igl
+python -m pip install libigl
 ```
 
 We provide a complete jupyter version of the tutorials and the full [documentation](igl_docs.md).
