 Advanced Installation
 =====================

+libEnsemble can be installed from ``pip``, ``uv``, ``Conda``, or ``Spack``.
 
 libEnsemble requires the following dependencies, which are typically
 automatically installed alongside libEnsemble:
 
 * Python_       ``>= 3.10``
 * NumPy_        ``>= 1.21``
 * psutil_       ``>= 5.9.4``

 * tomli_        ``>= 1.2.1``
+* gest-api_     ``>= 0.1,<0.2``
 
-Given libEnsemble's compiled dependencies, the following installation
-methods each offer a trade-off between convenience and the ability
-to customize builds, including platform-specific optimizations.
