 .SH DESCRIPTION
     init is the first userspace process started by the MontaukOS
-    kernel. It chains system services in sequence, then launches
-    the interactive shell.
+    kernel. It discovers system services from 0:/config/init.toml
+    and starts them in the order their tables appear in that file.
 
-    Each service is spawned as a child process. init waits for it
-    to exit before starting the next one. If a service fails to
-    spawn, init logs an error and continues to the next stage.
+    Each enabled service is spawned as a child process. Services may
+    run in the background or block startup until they exit. Disabled
+    services are logged and skipped.
 
     Log output is timestamped and color-coded:
 
         HH:MM:SS   INFO   init  Starting dhcp
         HH:MM:SS     OK   init  dhcp finished (pid 1)
 
-.SH BOOT SEQUENCE
-    The following services are started in order:
+.SH CONFIGURATION
+    Each service is declared as a named TOML table:
 
-        1. 0:/os/dhcp.elf     Obtain network configuration via DHCP
-        2. 0:/os/shell.elf    Launch the interactive shell
+        [services.dhcp]
+        path = "0:/os/dhcp.elf"
+        enabled = true
+        wait = false
 
-    After the shell exits, init enters an idle loop.
+    path is required. name controls the name shown in the boot log and
+    defaults to the table name. enabled and wait both default to true.
+    optional skips a service whose executable is not installed.
+
+    fallback names another configured service to start if spawning the
+    service fails. A service with fallback_only = true is available as
+    a fallback but is not started during the normal pass.
+
+    After all foreground services exit, init enters an idle loop.
 
 .SH LOG LEVELS
     init uses four log levels, each with a distinct color:
