+## FAQ
+
+> Will Xiao ever be public again?
+
+No.
+
+> Will Xiao ever support Slash Commands?
+
+Most likely, no. Many of the commands in Xiao were written with the message content intent in mind,
+and given her status as a private bot I see no reason to change that. Plus, kitchen-sink bots
+really _don't_ work with Slash Commands, they just clog up the list.
+
+> Can I use part of Xiao's code (i.e. a command) in my bot?
+
+I don't really care, but please give credit in some form if you do so. You'll also be subject to
+`LICENSE.md`, and I won't provide you with any support if it doesn't work.
+
+> Can I host Xiao myself?
+
+If you want, good luck. Setting her up is a pretty difficult task.
+
+> Do I need every API key, emoji ID, etc.?
+
+No, but some commands may not work without them.
+
+> Do I need to set up Redis?
+
+Yes, several commands and functions rely on it.
+
+> Do I really need to install Wine and Wine32 on Linux?
+
+Only if you want to use the DECTalk command.
+
+> Where can I find DECTalk?
+
+Good question! I don't even remember where I found it, and I really can't help you. While it's
+probably considered abandonware and I doubt anyone would go after a private Discord bot of all
+things, I'm not taking any chances.
