 ###### *Mono specific*
 *If you are using Wine, you need to mark both ClassicalSharp.exe and Launcher.exe as executable, then type this into the terminal: `./Launcher.exe`
 If you are using Mono, you just need to type `mono Launcher.exe` into the terminal.*
 
-*Also when using older mono versions, you may need to run `mozroots --import --sync` to import trusted root certificates, otherwise you will get an 'Error writing headers' exception.*
+*You may get TrustFailure/SendFailure errors trying to download https:// texture packs, [see here](https://github.com/duplicati/duplicati/wiki/SSL-TLS-support-in-Mono) for how to fix.*
+
+*For wine, you'll need to navigate to the internal folder of mono (usually ~/.wine/drive_c/windows/mono/mono-2.0/lib/mono/4.5/), and use say 'wine mozroots.exe' instead.*
 
 ###### *Windows specific*
 *If you are stuck using the built-in OpenGL 1.1 software renderer, you can use the MESA software renderer from either [here](http://download.qt.io/development_releases/prebuilt/llvmpipe/windows/) or [here](https://wiki.qt.io/Cross_compiling_Mesa_for_Windows) for slightly better performance. Typically though, this occurs because you have not installed GPU drivers.*
 
 #### Tips
 * Press escape (after joining a world) or pause to switch to the pause menu.
-* Pause menu -> Key bindings lists all of the key combinations used by the client. 
+* Pause menu -> Options -> Controls lists all of the key combinations used by the client. 
 * Note that toggling 'vsync' to on will minimise CPU usage, while off will maximimise chunk loading speed.
 * Press F to cycle view distance. A smaller number of visible chunks can improve performance.
 
 * If the server has disabled hacks, key combinations such as fly and speed will not do anything.
