 ## Getting started
 
 We recommend using our toolbox with Linux or with the Windows Subsystem for Linux (WSL2). Much of the core
 functionality works fine on Windows, but PyTorch's full feature set is only available on Linux. Read [more about
 WSL here](docs/WSL.md).
 
 Clone the repository into a subfolder of the current directory:
-```shell script
+
+```shell
 git clone --recursive https://github.com/microsoft/InnerEye-DeepLearning
 cd InnerEye-DeepLearning
 git lfs install
 git lfs pull
 ```
+
 After that, you need to set up your Python environment:
+
 - Install `conda` or `miniconda` for your operating system.
 - Create a Conda environment from the `environment.yml` file in the repository root, and activate it:
-```shell script
+
+```shell
 conda env create --file environment.yml
 conda activate InnerEye
 ```
-- If environment creation fails with odd error messages on a Windows machine, please [continue here](docs/WSL.md).

+Now try to run the `HelloWorld` segmentation model - that's a very simple model that will train for 2 epochs on any
 machine, no GPU required. You need to set the `PYTHONPATH` environment variable to point to the repository root first.
 Assuming that your current directory is the repository root folder, on Linux `bash` that is:
-```shell script
+
+```shell
 export PYTHONPATH=`pwd`
 python InnerEye/ML/runner.py --model=HelloWorld
 ```
+
 (Note the "backtick" around the `pwd` command, this is not a standard single quote!)
 
 On Windows:
-```shell script
+
+```shell
 set PYTHONPATH=%cd%
 python InnerEye/ML/runner.py --model=HelloWorld
