 LibreOffice Wrapper
 *******************
 
+Windows using DLL (shared library)
+----------------------------------
+
 A very simple example can be found here: :download:`TestLibreOffice.ods`.  You will need to download the release 32-bit __stdcall shared library for windows from :sfdownloads:`sourceforge <shared_library/Windows/32bit__stdcall_calling_convention>` or from :bbbinaries:`the development server <shared_library/Windows/32bit__stdcall_calling_convention>`.  Place the downloaded DLL in c:\\CoolProp
 
-.. warning::
-    
-    This only works on windows.  There is currently no easy way to call shared libraries from linux or OSX.
+Linux using python
+------------------
+
+1. You will need two files - :download:`coolprop.py` and :download:`TestLibreOfficePy.ods`
+
+2. At the command prompt do something like::
+
+    # Make a folder for the script to reside in 
+    mkdir -p ~/.config/libreoffice/4/user/Scripts/python/ 
+    # Copy the dowloaded .py file to the folder you made (adjust download path as necessary) 
+    cp ~/Downloads/coolprop.py ~/.config/libreoffice/4/user/Scripts/python/ 
+
+    # Install python script provider (uses python 3) 
+    sudo apt-get install libreoffice-script-provider-python 
+    # pyton scripting in LibreOffice uses python3, make sure we populate the right python site-packages folder 
+    sudo apt-get install python3-pip 
+    sudo pip3 install Cython 
+    # Compile CoolProp v5+ manually 
+    # you need to have numpy and matplotlib already - you can do sudo apt-get install python3-matplotlib 
+    git clone http://github.com/CoolProp/CoolProp --recursive 
+    cd CoolProp/wrappers/Python 
+    sudo python3 setup.py install
