+====== OOWOW auto-install disk ======
+Sometimes, your device has limited access (no keyboard, network, etc ... ), and we need to update eMMC storage content automatically. What did we need? Just  [[#preparation|prepare a special removable disk]]
+<WRAP tip >
+These features can work from SD / USB removable disk
+</WRAP>
+===== Preparation =====
+  * [[/software/oowow/how-to/start#write-oowow-image-to-removable-storage|write OOWOW system image to removable device]]
+  * create dump image for eMMC by any way fox example from oowow or manually by hands
+  * create [[#auto-install-config|autoinstall config]]
+===== Autoinstall =====
+  * Plug prepared removable disk into your device
+  * Reboot into OOWOW mode by any way - just reset your device if it can boot up from this removable disk or by a special shortcut or i2c command if device has embedded oowow
+  * Wait for autoinstallation, all processes must go automatically
+  * Reboot to upgraded system
 ===== Image filename rules =====
-''BOARD.*.emmc.img.zst'' put into root on 2n dump SD partition
+''BOARD.*.emmc.img.zst'' put into root on 2n ''SD'' partition with label ''dump''
-===== Auto-install config setup  ======
+===== Auto-install config ======
+Stored into ''rescue/config/autoinstall'' on 1st ''SD'' partition with label ''rescue''
+==== Auto-install config format ====
+```config /config/autoinstall

+# BOARD         board name [ VIM1 | VIM2 | VIM3 | VIM3L |  Edge | Edge2 | VIM1S | VIM4 ]
+# .BYTES-bytes   write size limitation tag
