Hello,
I've just added the minimum required versions for every dependency in README.md.
That may be useful for compiling on debian.

About the battery... Could you check, and edit if necessary, the battery name in
`src/config.zig`? By default it's BAT1, but you may have a different one in
`/sys/class/power_supply/`.
If you have no battery (desktop pc) I have yet to implement support for that,
sorry. Feel free to submit a patch if interested :).
