+Managing Cheats
+===============
+
+Ryujinx now has native cheats/runtime mods support!  
+It implements full support Atmosphere style cheats (except game pausing/resume): 
+https://github.com/Atmosphere-NX/Atmosphere/blob/master/docs/features/cheats.md
+
+## Installation of Atmosphere Cheats
+
+Two good places to acquire Atmosphere cheats are:
+
+- https://github.com/WerWolv/EdiZon_CheatsConfigsAndScripts/tree/master/Cheats (general switch cheats)
+- https://yuzu-emu.org/wiki/switch-mods/ (emulator-specific mods such as high FPS, ultrawide, etc...)
+
+Inside the cheat `zip`, `rar`, or other archive format, there is usually a file structure like this:
+
+```
+Cheat_Name\cheats\0123456789ABCDEF.txt
+```
+
+Where `0123456789ABCDEF` will vary according to the game and the cheat (this is the build id of the executable the cheat attaches itself to). A cheat can also contain several `txt` files. **Cheats are game-specific and version-specific, they will not work if transferred from one game to another or to an incompatible update of the game.**
+
+To install the cheat: 
+
+- Open Ryujinx, right-click the game you wish to install the cheat and select to open its `Mod directory`;
+- A directory like this will open: `Ryujinx\mods\contents\XXXXXXXXXXXXXXXX\`, `XXXXXXXXXXXXXXXX` will be the id of the chosen game;
+- Extract the cheat archive to the mod directory, keeping the cheat name: `Ryujinx\mods\contents\XXXXXXXXXXXXXXXX\Cheat_Name\cheats\<all the txt files>`.
+
+## Activating/Deactivating cheats
+
+Currently, all cheats are automatically enabled and cannot be disabled, so mixing, for instance, 60, 90 and 120 fps cheats may cause a conflict. 
+
+One alternative is to create a directory `disabled_cheats` in the mod directory and move all unused cheats there. Another one is to prepend something to the file name, for instance `off_0123456789ABCDEF.txt` as a valid cheat must not have anything but `0123456789ABCDEF.txt` in its name.
+
+The .txt files can also contain several cheats that may conflict. To switch off individual cheats inside a .txt file first **backup the .txt file** to something like `bak_0123456789ABCDEF.txt` (this will also prevent the backup to be loaded as a cheat). Next, in the .txt file, there will be sections, each with a name within `[ ]` brackets and filled with sequences of letters and numbers (the code of the cheat), for instance:
+

+78000000 0002A1C4
+61000000 00000000 00000005
+```
+
+To disable the time cheat, just remove its section and the code:
+
+```
+[New Super Mario Bros. U Deluxe]
+
+[Start with 99 Lives]
+58000000 00CC9860
