+FAQ
+---
+
+Q: What platforms are supportded?  
+A: keynav should work on nearly any Unix-like that runs X11. It has been
+confirmed to work on extremely varied GNU/Linux systems (incuding RPM-based,
+Debian derivatives, musl-based systems, and Arch), and FreeBSD. If you get it to
+run elsewhere, please let me know so I can add it to the list. If you try to run
+it on another Unix-like and have trouble, please get in touch and I'll try to
+help. If attempting to run elsewhere, note that we currently have a dependency
+on GNU Make (gmake), and it hasn't been tested with many compilers yet.
+
+Q: Does it work on Android/Windows/Wayland/iOS/...?  
+A: Sadly, no; keynav is totally dependent on X11, and porting it to any other
+graphical system would really be a clone/rewrite. Although I am aware of no
+exact analogues on other systems, I suggest looking into Tasker (Android),
+AutoHotKey (Windows), and AppleScript (macOS). If you find something that works,
+let me know and I'll consider adding it to this list.
+
+Q: Can I use keynav to scroll?  
+A: Yes! X11 represents mouse scrolling as key presses, so you just add the
+relevant stanza to your keynavrc.  Mouse buttons are
+1=left, 2=middle, 3=right, 4=scroll-up, 5=scroll-down. So for example to scroll
+up with i and down with e:
+    i click 4,end
+    e click 5,end
+or to keep scrolling without having to re-invoke keynav:
+    i click 4
+    e click 5
