+# Zig Rewrite
+
+## Config Options
+
+res/config.ini contains all of the available config options and their default values.
+
+### Additions
+
++ border\_fg has been introduced to change the color of the borders.
++ term\_restore\_cursor\_cmd should restore the cursor to it's usual state.
++ sleep\_key and sleep\_cmd.
++ log\_path is used to store ly.log and ly.log.old for debugging purposes (pretty much nothing is logged currently).
+
+Note: sleep\_cmd is unset by default, meaning it's hidden and has no effect. 
+
+### Changes
+
++ xinitrc can be set to null to hide it.
++ blank\_password has been renamed to clear\_password.
+
+### Removals
+
++ wayland\_specifier has been removed.
+
+## Save File
+
+The save file is now in .ini format.
+
+Example:
+
+```ini
+user = ash
+session_index = 0
+```
+
+## Misc
+
++ getty@tty2 has been added as a conflict in res/ly.service, so if it is running, ly should still be able to start.
++ XDG\_CURRENT\_DESKTOP is now set by ly.
++ LANG is no longer set by ly.
++ X Server PID is fetched from /tmp/X{d}.lock to be able to kill the process since it detaches.
