 Use of this patch violates the [KF2 EULA](https://store.steampowered.com/eula/232090_eula_0) provisions that prohibit disassembling or modifying game files.  
 If this is a problem for you, use [SafeMutLoader](https://github.com/GenZmeY/KF2-SafeMutLoader/), which is completely legal.  
 
-## Linux
-### Dependencies
+## Warning
+Applying this patch may require you to do things like execute a script, edit a binary file, restore execution rights after replacing a file. For this reason, **I can only recommend using this patch if you have full access to the system**, for example if you are using your own server or renting a VPS (virtual private server).  
+
+If you are using a game hosting service, then performing the above actions may be difficult or even impossible, so I would recommend using [SafeMutLoader](https://github.com/GenZmeY/KF2-SafeMutLoader/) in this case.  
+
+## Applying the patch (easy way)
+Take the patched file from the [releases](https://github.com/GenZmeY/KF2-Ranked-Patch/releases):  
+For windows: `KFGame.exe`  
+For linux: `KFGameSteamServer.bin.x86_64`  
+
+And place it on your server at this path (replace the existing file):  
+`<kf2-server>/Binaries/Win64`
+
+In the case of a linux system, make sure that after replacing the file has an execution flag and if it does not - add it using `chmod` like this:  
+`chmod +x <path_to_KFGameSteamServer.bin.x86_64>`  
+
+## Applying the patch (manually)

+## How it works
+This patch modifies the `KFGameInfo::SetGameUnranked()` function so that it does nothing - this prevents the server from going into an unranked state.  
+The patch also modifies the `KFGameInfo::ValidateForXP()` function so that it always returns true. `ValidateForXP()` prevents XP from being gained for killing custom zeds and using custom weapons - modifying this function makes it possible to gain XP in these cases.  
+
+The patch for Linux is a bash script that searches for and patches these functions in the executable file, works with any version of the KF2 server.  
+In the case of Windows, there is no automation and the work to find the necessary functions was done manually, so replacing the specified hex sequences is relevant only for a specific version of the KF2 server (currently 1150 and 1150v2).

 ## Notes
 - Game updates and integrity checks replace the executable file (`KFGameSteamServer.bin.x86_64` / `KFServer.exe`) with original one, so after these events the patch must be applied again.
