-===== Install =====
+==== sysupgrade ====
-  * ''-n'' doesn't save old config
+  * This downloads the latest ''sysupgrade.bin'' and installs it
-  * ''--force'' forces the flash
-  * ''-v'' more verbose

-=== Google DNS ===
+====== LuCI ======
-  * Some devices hard-code Google DNS, and this bypasses NextDNS and the blocklists set there
+  * http://192.168.1.1
-  * So the solution to this is to block any requests to Google DNS
