+# Portability
+
+succade uses [libkita](https://github.com/domsson/libkita) to manage child processes. libkita uses `epoll`, which is Linux only. I've attempted to port libkita to BSD using `kqueue`, but couldn't get it to work reliably (yet).

 # Installation 
 
 Make sure you have `lemonbar` (obviously), `gcc` (for compiling the source code) and all dependencies, as listed above, installed. If `inih` is not available in your distribution, just replace `./build` with `./build-inih` below and you should be good to go.

+succade is public domain software, do with it whatever you want. However, succade uses [`inih`](https://github.com/benhoyt/inih), which is under the New BSD license.

 # Motivation 
 
 With projects like [polybar](https://github.com/polybar/polybar), the question for the relevance of succade is justified. Personally, I prefer succade - and similar solutions, like [Captain](https://github.com/muse/Captain) - because they enforce the separation of concerns as described by the [UNIX philosophy](https://en.wikipedia.org/wiki/Unix_philosophy).
