 # Using VTS in a Jupyter notebook
 
-This is likely to change once `python` scripting is formally supported by `VTS`.  
+This information will likely change as more support for `python` and `.NET` is introduced.  
 
-## macOS installation details
-
-This is a record of how I got `vts` working in `JupyterLab`.
+## Installation details
 
 ### Step 1: Install .NET 6
 
 You will need version 6 of .NET which is available from Microsoft below
 
 https://dotnet.microsoft.com/en-us/download/dotnet/6.0
 
-I saved everything to `$HOME/Documents/Code/dotnet6`
+
+***On MacOS:***
+Save everything to `$HOME/Documents/Code/dotnet6`
 
 Do not forget to update your `~/.bash_profile` or whatever you use so that this directory is in your path.  Also define `DOTNET_ROOT` 
 
     PATH=$PATH:$HOME/Documents/Code/dotnet6
 
     export DOTNET_ROOT=$HOME/Documents/Code/dotnet6
 
-### Step 2: Install VTS
-
-Follow the guidelines at https://github.com/VirtualPhotonics/VTS/wiki/Getting-Started-on-Mac  Briefly, clone the `.git` repo 
+### Step 2: Clone the scripting repository
 
     git clone https://github.com/VirtualPhotonics/vts.git
 
-This will create the directory `vts` that is needed for the next step
-
-Install both `powershell` and `nuget` using [Homebrew](https://brew.sh)
-
-    brew install powershell
-    brew install nuget
+### Step 3: Download the VTS libraries
 
-Now build VTS.  If you don't have `matlab` don't worry, it seemed to work fine without completing the `matlab` tests
+Get the latest VTS libraries for the specific platform from [releases](https://github.com/VirtualPhotonics/Vts.Scripting.Python/releases) and extract them into the **libraries** folder under **scripting**. 
 
-    pwsh
-    cd vts
-    ./BuildTestRelease.ps1 
-    exit
-
-### Step 3: Install pythonnet
+### Step 4: Install pythonnet
 
     pip install pythonnet
 
-Because `pythonnet` under macOS (or linux) defaults to `mono`, two more things need to added to `~/.bash_profile`
