-## Setting up the conda environment on personal computers
 
-* **Install conda**
-https://conda.io/docs/user-guide/install/
+## Setup Instructions
 
-* **Install the environment**
-  * On Mac:
-  	* Open a terminal and navigate to the workshop git repository
-  	* Run the command: `conda env create -f environment.yml`
-        <br/>
-  * On Linux:
-  	* Open a terminal and navigate to the workshop git repository
-  	* Run the command: `conda env create -f environment_linux.yml`
-        <br/>
-  * On Windows
-    * Open Anaconda prompt and navigate to the workshop git repository
-    * Run the command: `conda env create -f environment.yml`
-    <br/><br/>
-* **Check installation**
+The setup is based on the Conda distribution for Python called Anaconda
+(https://www.anaconda.com/products/individual).
 
-  * On **Linux**/**Mac** - open a terminal
+### I. Install Anaconda
 
-  * On **Windows** - open Anaconda prompt
+1. If you don’t have Anaconda yet, download and install Anaconda from
+   https://www.anaconda.com/products/individual, or, in case you work on a ETH-managed
+   computer, install Anaconda via the
+   [ETH AppV Software Kiosk](https://app.ethz.ch/kiosk).
 
-and run the following commands:
-~~~~
-conda activate machine_learning_workshop
-jupyter notebook
-~~~~
+### II. Install Conda environment
 
-(For some versions of Anaconda on **Windows** you might have to run just **activate machine_learning_workshop** intead of **conda activate ...**)
+#### on MacOS:
 
+1. Open Terminal.app, change directory to the directory with workshop materials
+   (`$ cd path/to/dir`) and run:
 
-in case your installation worked your browser should open jupyter.
+       $ conda env create -f environment.yml
+
+#### on Linux
+
+1. Open Terminal, change directory to the directory with workshop materials
+   (`$ cd path/to/dir`) and run:
+
+       $ run conda env create -f environment_linux.yml
+
+#### on Windows
+
+1. Start the Anaconda Navigator and Select "Environments"
+2. Press "Import Environment" Button.
+3. Click at the folder icon; using the File Selection Dialog navigate to the to the directory with workshop materials and select `environment.yml` file.
+4. Press "Import" Button.
+5. Click on the black triangle and from the dropdown list select "Open Terminal".
+
+### III. Check installation
+
+1. In the Terminal run:
+
+      $ conda run -n machine_learning_workshop_2021 python -c "import tensorflow, matplotlib, numpy, pandas; print('OK')"
+
+   Your setup is OK if this command returns without any error message.
+
+2. Check if you can start JupyterLab in your Web browser by running in the Terminal:
+
+      $ conda run -n machine_learning_workshop_2021 jupyter lab
+
+
+## Using JupyterLab
+
+The course content is provided as Jupyter Notebooks. Please make sure to familiarize
+yourself with
+[JupyterLab Interface](https://jupyterlab.readthedocs.io/en/latest/user/interface.html).
+
+The Setup Instructions include information on how to start JupyterLab in a Web browser.
+
+## Preparation Script
+
+The workshop materials contain a `00_numpy_pandas_matplotlib_intro.ipynb`
+Jupyter Notebook with an introduction to NumPy, pandas and Matplotlib libraries, which we
+are used without further introduction during the workshop. Please prepare yourself and
+go through the notebook.
