 This is a list of frequently asked questions, with their answers. It's by no
 means an exhaustive list.
 
+## I use a mix of different operating systems, can I still use Flamenco?
+
+Yes, absolutely. To support multiple platforms, first configure your Manager for
+its own platform (so if you run that on Linux, use Linux paths). Then you can
+use [Two-way Variables][twovars] to translate those paths to the other
+platforms.
+
+Do note that Flamenco was developed on Linux, for the Linux-only [Blender
+Studio][studio]. You may find issues that the developers did not run into
+themselves. If you do, please [report a bug][bug].

+## My Worker cannot find my Manager, what do I do?
+
+First check the Manager output on the terminal, to see if it shows any messages
+about "auto-discovery" or "UPnP/SSDP". Most of the time it's actually Spotify
+getting in the way, so make sure to close that before you start the Manager.
+
+If that doesn't help, you'll have to tell the Worker where it can find the
+Manager. This can be done on the commandline, by running it like
+`flamenco-worker -manager http://192.168.0.1:8080/` (adjust the address to your
+situation) or more permanently by [editing the worker configuration
+file][workercfg].
