+## Frequently asked questions
+
+Make sure you check these before making an issue!
+
+### NSP installs
+
+- **I keep getting 'invalid NCA'/'missing sigpatches' or weird FS/ETicket errors...**
+
+  Check the following:
+
+  - The NSP is converted from XCI (using tools like 4NXCI)? Then you need extra patches.
+
+  - Do you have all the required patches?
+
+    If you have just updated to a new console version and this error happens, try to redownload them.
+
+- **Goldleaf freezes and Quark doesn't respond/complains when I launch it...**
+
+  - Do you have USB set-up correctly? Check how to do so [here](#quark-and-remote-browsing).
+
+    - If you do have USB corrently set-up, Quark shouldn't complain. If it does, try doing the setup again to ensure it is done fine.
+
+  - Also, make sure you're launching Quark **after having launched Goldleaf. Goldleaf needs to be opened first.**
+
+  - Are you using the latest version of both Goldleaf and Quark? Double-check it just in case, since this is a very common mistake.
+
+- **I can't launch Quark / Quark is giving me errors on Linux...**
+
+  - Quark is a little bit fucky on Linux. Make sure to check [the setup](#linux) for some more information about the matter.
