 Installation
 ~~~~~~~~~~~~
-Step 1:
-You'll need SciKit-SurgeryUtils installed on your system. Provided you have Python installed on 
-your system you should be able to run ...
-::
-
-  pip install scikit-surgeryutils
-
-to install SciKit-SurgeryUtils and its dependencies (including SciKit-SurgeryCore).
-For the third part of the tutorial you'll also need SciKit-SurgeryArUcoTracker
-
-::
 
-  pip install scikit-surgeryarucotracker
+Packages, other requirements, and virtual environments
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
-If you don't have Python installed, we 
-recommend downloading an installer for your platform directly from `python.org`_.
-
-Virtual environments
+Python virtual environments
 ~~~~~~~~~~~~
 Virtualenv, venv, conda or pyenv can be used to create virtual environments to manage python packages.
-You can use conda env by installing conda for your OS (`conda_installation`_) and use the following yml file with all dependencies.
+If you don't have Python installed, we recommend downloading an installer for your platform directly from `python.org`_.
+For the case of conda, please create a VE using the following commands in your terminal:
+
 ::
-   ## Create scikit-surgerytutorial01VE.yml in your favorite location with the following content:
-   ##
-   ##  scikit-surgerytutorial01VE.yml
-   ##
-   ## Some useful commands to manage your conda env:
-   ## LIST CONDA ENVS: conda list -n *VE # show list of installed packages
-   ## UPDATE CONDA: conda update -n base -c defaults conda
-   ## INSTALL CONDA EV: conda env create -f *VE.yml
-   ## UPDATE CONDA ENV: conda env update --file *VE.yml --prune
-   ## ACTIVATE CONDA ENV: conda activate *VE
-   ## REMOVE CONDA ENV: conda remove -n *VE --all
