 ## Things still needed to be done
 - Fix bugs that slipped by
 - More options for chat rendering

+## Linux? MacOS?
+Sorry the GUI version is only avaliable for Windows :( but there is a command line version avaliable.
+This is a cross platform client that can do the main functions of the program without a GUI. It works on Windows and Linux, haven't tested it on MacOS though. 
+[Some documentation here](https://github.com/lay295/TwitchDownloader/blob/master/TwitchDownloaderCLI/README.md), for example, you could copy/paste this into a .bat file on Windows and you can download a VOD, download chat, then render it in a single go. I've never really made a command line utility before, so things may change in the future. If you're on Linux, make sure fontconfig and libfontconfig1 are installed. (apt-get install fontconfig libfontconfig1)
