+## FAQ
+
+Frequently asked questions:
+
+- Q: Why is the map black when loading for the first time?
+  
+  - A. You must obtain a free API key from either (or both) [MapTiler](https://cloud.maptiler.com/auth/widget?next=https://cloud.maptiler.com/maps/) which reuqires no credit/debit card, or [Mapbox](https://account.mapbox.com/) which does require a credit/debit card, but as of writing, you will get 200K free requests per month, which you will never go over by yourself.
+
+- Q: How come when I change my color table or API key, nothing happens after hitting apply?
+
+  - A. As of right now, you must restart Supercell-Wx in order to apply these changes. In future iterations, this will no longer be an issue.
+   
+- Q. Is it possible to get dark mode?
+ 
+  - A. In Windows, make sure to set the flag `-style fusion` at the end of the target path of the .exe
+    - Example: `C:\Users\Administrator\Desktop\Supercell-Wx\bin\supercell-wx.exe -style fusion`
+  - A. In Linux, if you're using KDE, it should automatically follow your theme settings.
