+# Advanced Reboot Web UI (luci-app-advanced-reboot)
+
+## Description
+This package allows you to reboot to an alternative partition on supported (dual-partition) routers and to power off (power down) your OpenWrt/LEDE Project device.
+
+## Supported Devices
+Currently supported dual-partition devices include:
+- Linksys WRT1200AC
+- Linksys WRT1900AC
+- Linksys WRT1900ACv2
+- Linksys WRT1900ACS
+- Linksys WRT3200ACM
+- Linksys E4200v2
+- Linksys EA4500
+- Linksys EA8500
+
+If you're interested in having your device supported, please post in [LEDE Project Forum Support Thread](https://forum.lede-project.org/t/web-ui-to-reboot-to-another-partition-dual-partition-routers/3423).
+
+## Screenshot (luci-app-advanced-reboot)
+![screenshot](https://raw.githubusercontent.com/stangri/screenshots/master/luci-app-advanced-reboot/screenshot01.png "screenshot")
+
+## How to install
+Install ```luci-app-advanced-reboot``` from Web UI or connect to your router via ssh and run the following commands:
+```sh
+opkg update
+opkg install luci-app-advanced-reboot
+```
+
+## Notes/Known Issues
+- When you reboot to a different partition, your current settings (WiFi SSID/password, etc.) will not apply to a different partition. Different partitions might have completely different settings and even firmware.
+- If you reboot to a partition which doesn't allow you to switch boot partitions (like stock Linksys firmware), you might not be able to boot back to OpenWrt/LEDE Project unless you reflash it, loosing all the settings.
+- Some devices allow you to trigger reboot to alternative partition by interrupting boot 3 times in a row (by resetting/switching off the device or pulling power). As these methods might be different for different devices, do your own homework.
+
+## Thanks
+I'd like to thank everyone who helped create, test and troubleshoot this package. Without contributions from [@hnyman](https://github.com/hnyman) and [@jpstyves](https://github.com/jpstyves) it wouldn't have been possible.
