+## OS image or ROM
+An operating system (OS) is system software that manages computer hardware, software resources, and provides common services for computer programs. 
+Popular, custom operating systems for mobile devices based on Android are 
+- [LineageOS](https://lineageos.org/)
+- [/e/OS](https://e.foundation/e-os/) or
+- [LineageOS for microG](https://lineage.microg.org/)
+- and many others.
+
+Often, the related OS images are called 'ROM'. 'ROM' stands for *R*ead-*o*nly *m*emory, which is a type of non-volatile memory used in computers
+for storing software that is rarely changed during the life of the system, also known as firmware.
+
+# Recovery Image
+A custom recovery is used for installing custom software on your device.
+This custom software can include smaller modifications like rooting your device or even
+replacing the firmware of the device with a completely custom ROM. .
+
+OpenAndroidInstaller works with the [TWRP recovery project](https://twrp.me/about/).
