 # Installation prerequisite
 
 In principle, any Conda/Mamba distribution will work. A few Conda/Mamba options are:
-- [Mambaforge](https://github.com/conda-forge/miniforge#mambaforge)
-- [Miniforge](https://github.com/conda-forge/miniforge#miniforge-pypy3)
+- [Miniforge](https://github.com/conda-forge/miniforge#miniforge-pypy3) (recommended as it includes mamba)
 - [Anaconda](https://www.anaconda.com/download)
 - [Miniconda](https://docs.conda.io/en/latest/miniconda.html)
