# Basix
Basix is a finite element definition and tabulation runtime library.
Basix allows users to:
- evaluate finite element basis functions and their derivatives at a set
of points;
- access geometric and topological information about reference cells;
- apply push forward and pull back operations to map data between a
reference cell and a physical cell;
- permute and transform DOFs to allow higher-order elements to be use on
arbitrary meshes; and
- interpolate into a finite element space and between finite element
spaces.
Basix includes a range of built-in elements, and also allows the user to define
their own custom elements.
Basix is one of the components of FEniCSx, alongside
[UFL](https://github.com/fenics/ufl),
[FFCx](https://github.com/fenics/ffcx), and
[DOLFINx](https://github.com/fenics/dolfinx).
## Installing Basix
