+This is my `~/.config/sway/config`, and `…config.d/`. The main config contains
+thinks that I have felt as essential or otherwise felt like putting there,
+but as I love include directives, a lot is in the config.d.

+`~/.config/sway/config.d/` where `*.conf` is included by my sway config.
+Thus this `README.md` is not read, even if I happened to carelessly
+copy-paste it in.
+
+* `autostart-communication.conf` - chat/communication apps I am expected to have
+  open or at least check at times
+* `autostart-fineid.conf` - Finnish electric identity card, that I also use as SSH key
+* `autostart-utilities.conf` - general utilities, like `nm-applet` or VPN etc.
+* `grimshot.conf` - screenshotting keybinds using `grimshot`
+* `i3-selenized-dark.conf` - selenized dark colour scheme
+* `keyboard.conf` - keyboard configuration
+* `media.conf` - media key configuration and autostarts related to it
+* `pointer-accel.conf` - pointer/mouse configuration, mainly setting acceleration
+  profile to `flat`
+* `README.md` - you are currently reading this :wink:
+* `sedric.conf` - configuration specific to my laptop hostnamed `sedric`
+* `swaybar.conf` - `swaybar` configuration
+* `swayidle.conf` - `swayidle` configuration/autostart
+* `wlsunset-kotka.conf` - `wlsunset` configuration/autostart for my hometown for when
+  I happen to visit for longer period of time
+* `wlsunset-lauttasaari.conf` - `wlsunset` configuration for my home neighbourhood
+* `zz-floating.conf` - configures windows that should float. For some reason
+  that is inherited from my `i3` config, it tells to put float rules above the
+  last line, so it should be read last and `z` is the last letter of English
+  alphabet so it will hopefully be read last.
