 ## Installation
 
-For the best polyglot experience on Linux, we recommend using [Pixi](https://pixi.sh/latest/) to manage your development environment. Environment creation support for Pixi on Windows and MacOS ARM is currently limited for R packages. Installation of the R dependencies in Pixi is more difficult, because Pixi does not support [post-link scripts](https://github.com/prefix-dev/pixi/issues/1573) and the bioconda channel for bioconductor packages does not yet support [osx-arm64](https://github.com/bioconda/bioconda-recipes/issues/33333).
+For the best polyglot experience on most platforms, we recommend [renv](https://rstudio.github.io/renv/articles/renv.html) to manage the R and Python dependencies, see below for instructions.

 In a clean Linux shell without any active Python (`deactivate`) or Conda environments (`conda deactivate`), you can install all dependencies with the following command:
 
 ```bash
 pixi install -a
 ```
