 --------------------------------------------------
 
 The first step is to set up a conda environment and install glum in editable mode.
+The project uses [pixi](https://pixi.sh/latest/) for managing the environment. If you don't have pixi installed, start by [installing it](https://pixi.sh/latest/#installation).
 We strongly suggest to use ``mamba`` instead of ``conda`` as this provides the same functionality at much greater speed.
