-XMRig is a high performance, open source, cross platform RandomX, KawPow, CryptoNight and [GhostRider](https://github.com/xmrig/xmrig/tree/master/src/crypto/ghostrider#readme) unified CPU/GPU miner and [RandomX benchmark](https://xmrig.com/benchmark). Official binaries are available for Windows, Linux, macOS and FreeBSD.
+![x4x_spash](https://user-images.githubusercontent.com/128682335/227436274-10a8321c-7b75-4f70-a304-e7ab34f74e16.png)
 
-## Mining backends
-- **CPU** (x64/ARMv7/ARMv8)
-- **OpenCL** for AMD GPUs.
-- **CUDA** for NVIDIA GPUs via external [CUDA plugin](https://github.com/xmrig/xmrig-cuda).
+## Description
 
-## Download
-* **[Binary releases](https://github.com/xmrig/xmrig/releases)**
-* **[Build from source](https://xmrig.com/docs/miner/build)**
+**x4x** is a strict XMRIG's fork incorporating randomX algorithm variant for mining XDAG. It's based on the [Swordlet project](https://github.com/swordlet/xmrig/tree/xdag) using [XMRig 6.18.0](https://github.com/xmrig/xmrig/releases/tag/v6.18.0). It's specially designed to improve XDAG mining :
 
-## Usage
-The preferred way to configure the miner is the [JSON config file](https://xmrig.com/docs/miner/config) as it is more flexible and human friendly. The [command line interface](https://xmrig.com/docs/miner/command-line-options) does not cover all features, such as mining profiles for different algorithms. Important options can be changed during runtime without miner restart by editing the config file or executing [API](https://xmrig.com/docs/miner/api) calls.
+* **algorithms other than RandomX have been removed** at compilation (_CryptoNight, Argon2, KawPow and GhostRider_),
+* **_CUDA_ and _OpenCL_ support have been removed** at compilation too (_GPUs are useless to mine XDAG_).
+* **the fees have been set to zero** for improving mining and to avoid disconnections to XDAG mining pools, 
 
-* **[Wizard](https://xmrig.com/wizard)** helps you create initial configuration for the miner.
-* **[Workers](http://workers.xmrig.info)** helps manage your miners via HTTP API.
+## Available on theses OS/platforms :
+* Windows 10 x64 and upper.
+* Linux Ubuntu 18.04 / 20.04 / 22.04 / 22.10
+* Hive OS (Ubuntu 18.04)
+* FreeBSD 13.1
+* MacOS x64 darwin (10.5.x and upper)
+* CentOS 8
+
+## How to compile
+Check Github [wiki pages](https://github.com/FSOL-XDAG/xmrig-4-xdag/wiki#how-to-build).
