 # OneDriveAPI
+
+> Notice: Through the years I have enjoyed building and maintaining this code. Time however is scarse and as much as I would like to, I'm having too many projects to work on in my spare time, so I need to get rid of some, this unfortunately being one. I will therefore no longer maintain this code. Feel free to fork off of it and make your own version out of it. I'll be happy to link to it.
