 If you're using Google Chrome, please connect Sshwifty with HTTPS. Chrome will
 disable WebCrypt and many other APIs when the connection is not safe.
 
+### Can I serve Sshwifty under a subpath such as `https://my.domain/ssh`?
+
+The short story is NO. Sshwifty was designed based on an assumption that it will
+run as the only service under a given hostname, allowing web browsers to better
+enforce their data isolation rules. This is very important because Sshwifty
+saves user data locally.
+
+However, if you really want to put Sshwifty into a subpath, you can do so by
+taking advantage of the fact that Sshwifty backend interface and assets are
+always located under an URL prefix `/sshwifty`. You can thus redirect or proxy
+those requests to their new location.
+
+Keep in mind, doing so is really hacky, and it's not recommended by the author
+thus no support will be provided if you decide to go with that.
+
+### Why I can't add my own key combinations to the Console tool bar?
+
+The pre-defined key combinations are there mainly to make mobile operation
+possible as well as to resolve some hotkey conflicts. However, if efficiency is
+your first goal, please consider to use a software/on screen keyboard which is
+specially designed for terminal.
+
+And if that's not enough, connect a physical keyboard through Bluetooth or OTA
+could be a better alternative. This way you can type as if you're using a
+computer console.
+
+There are many good Bluetooth keyboards out there, for example the HHKB HYBRID
+TYPE-S, FILCO Majestouch Convertible 2 and GANSS ALT71D which is more afforable
+than the previous two. And if you don't want go get that serious, then a $10 one
+would also do.
+
+If you use JD.COM, you can purchase aformentioned keyboards with my links. I
+will be rewarded base on your purchase.
