 ## Python Virtual Environment
 
 ### Add new packages
-
 Try to install any new package using `conda install -c CHANNEL PACKAGE_NAME` (you can use `pip` if the package is only available there). Make sure your Python virtual environment is active (`conda activate YOUR_ENV`).
 
 ### Remove packages
 Uninstall packages using the same manager you used to install them `conda remove PACKAGE_NAME` or `pip uninstall PACKAGE_NAME`
 
-### Update your conda `environment.yaml`
-
-After installing or removing a package you can use the following command in your terminal to update your `environment.yaml` before publishing your pipeline. Note that we ignore the package version for `libfortran` to keep compatibility with Linux:

 ## How does it work?
 
 RAPIDS is formed by R and Python scripts orchestrated by [Snakemake](https://snakemake.readthedocs.io/en/stable/). We suggest you read Snakemake's docs but in short: every link in the analysis chain is atomic and has files as input and output. Behavioral features are processed per sensor and per participant.
