Description:
This UDL was available on old skunity forums but I was unable to bring back the light theme as I only had the dark saved, I've changed the light theme to have all the features as dark this UDL comes with syntax highlighting for conditions, effects, events, comments, strings, variables, etc...

Light Installation:

1. Unzip the provided download
   
2. Open up notepad++
3. at the top click language and then define your language
4. click "Import..." and add the light xml file
5. it should now by default open all .sk's with that UDL, you can also change the language manually from the language drop down menu

Dark Installation:

1. Same steps as Light Installation except import the dark xml instead of the light
2. After done, in notepad++ go to settings (at the top) and click style configurator
3. In the Select Theme drop down menu select Obsidian, hit save and you are all done
