+Miniforge uses the `conda` package management system and is based on Miniconda, which is a pared-down version of the full Anaconda Python distribution.
 
 [Installing Anaconda](https://docs.anaconda.com/anaconda/install/) takes longer and uses up more disk space, but provides you with more functionality, including Spyder (a Python-specific integrated development environment or IDE) and Jupyter, in addition to other immediately installed packages. Also, the interface of Anaconda is great if you are uncomfortable with the terminal.
 
-We recommend Miniconda for two reasons:
+We recommend Miniforge for these reasons:
 
 1. It's quicker and takes up less disk space.
 2. It encourages you to install only the packages you need in reproducible isolated environments for specific projects. This is generally a more robust way to work with open source tools.
+3. It uses `conda-forge` as the default channel for packages, which is our recommended way to get up-to-date, interoperable packages..
 
 Once you have `conda` via the Miniconda installer, the next step is to create an environment and install packages.
