 ### Detailed Instructions
 
+#### Web Install
+
+It is easier to use the web installer to flash GrapheneOS. However, it is recommended to use the manual method since it makes it possible to install an older version of GrapheneOS unlike the web installer which always installs the latest version.
+
+- Use the [web installer](https://grapheneos.org/install/web) to install GrapheneOS
+- Once installed, **do not** re-lock the bootloader by clicking `Lock bootloader` under the `Locking the bootloader` section
+- Proceed to the [patching section](#patching-grapheneos-cooking-pixeneos)
