 ## Features
 
-- Simple as C, meant to depend only on standard libc and basic unix system headers.
+- Simple as C, you only need a C compiler and standard unix libraries to build this.
-- Fully customizable: ALL strings, colors (with its ANSI keys) and most behavior.
+- Fully customizable, from strings, including action keys, to colors (I hope you know ansi escape codes)
-- Xorg[\*](https://github.com/javalsai/lidm/issues/79) and wayland sessions, while supporting the default user shell (if enabled in config)
+- Automatically detects xorg and wayland sessions, plus allowing to launch the default user shell (if enabled in config)
-- Init agnostinc (systemd, dinit, runit, openrc and s6).
+- Starts with many init systems (systemd, dinit, runit, openrc and s6).
-- Supports [fido yubikeys](./docs/yubikey.md) (via pam_u2f).

-# Yubikeys
-
-Quick reference explaining how yubikeys work for now.
-
-# Enable
-
-Yubikeys are disabled by default, to enable them activate a keybinding for it (`[functions] fido`) in the config file.
-
-Note that pressing this configured keybinding has no difference from trying to log in with an empty password, there's virtually no difference.
-
-`pam_u2f` must be configured with a registered key (`pamu2fcfg`).
-
-# Extra
-
-All my yubikey knowledge comes from the [pr that implemented this](https://github.com/javalsai/lidm/pull/89), please refer to it for extra details. Contributions to this documentation are welcome (explaining more in detail, potential issues... really anything that improves this).
-
-Allegedly this pam module configuration should work:
-
-```pam
-#%PAM-1.0
-
-auth sufficient pam_u2f.so cue
-auth       requisite    pam_nologin.so
-auth       include      system-local-login
-account    include      system-local-login
-session    include      system-local-login
-password   include      system-local-login
-```
-
-Also, I recommend giving the [arch wiki](https://wiki.archlinux.org/title/YubiKey) a read anyways.
