-XMRig High performance, open source, cross platform RandomX, CryptoNight, AstroBWT and Argon2 CPU/GPU miner, with official support for Windows.
+XMRig is a high performance, open source, cross platform RandomX, KawPow, CryptoNight and AstroBWT unified CPU/GPU miner. Official binaries are available for Windows, Linux, macOS and FreeBSD.
 
 ## Mining backends
-- **CPU** (x64/x86/ARM)
+- **CPU** (x64/ARMv8)
 - **OpenCL** for AMD GPUs.
 - **CUDA** for NVIDIA GPUs via external [CUDA plugin](https://github.com/xmrig/xmrig-cuda).

 ## Download
-* Binary releases: https://github.com/xmrig/xmrig/releases
-* Git tree: https://github.com/xmrig/xmrig.git
-  * Clone with `git clone https://github.com/xmrig/xmrig.git` :hammer: [Build instructions](https://github.com/xmrig/xmrig/wiki/Build).

 ## Usage
-The preferred way to configure the miner is the [JSON config file](src/config.json) as it is more flexible and human friendly. The command line interface 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 calls.

 ## Migration to v3
 Since version 3 mining [algorithm](#algorithm-names) should specified for each pool separately (`algo` option), earlier versions was use one global `algo` option and per pool `variant` option (this option was removed in v3). If your pool support [mining algorithm negotiation](https://github.com/xmrig/xmrig-proxy/issues/168) you may not specify this option at all.

+# Embedded benchmark
+
+You can run with XMRig with the following commands:
+```
+xmrig --bench=1M
+xmrig --bench=10M
+xmrig --bench=1M -a rx/wow
+xmrig --bench=10M -a rx/wow
+```
+This will run between 1 and 10 million RandomX hashes, depending on `bench` parameter, and print the time it took. First two commands use Monero variant (2 MB per thread, best for Zen2/Zen3 CPUs), second two commands use Wownero variant (1 MB per thread, useful for Intel and 1st gen Zen/Zen+ CPUs).
+
+Checksum of all the hashes will be also printed to check stability of your hardware: if it's green then it's correct, if it's red then there was hardware error during computation. No Internet connection is required for the benchmark.
+
+Double check that you see `Huge pages 100%` both for dataset and for all threads, and also check for `msr register values ... has been set successfully` - without this result will be far from the best. Running as administrator is required for MSR and huge pages to be set up properly.
+
+![Benchmark example](https://i.imgur.com/PST3BYc.png)
+
+### Benchmark with custom config
+
+You can run benchmark with any configuration you want. Just start without command line parameteres, use regular config.json and add `"benchmark":"1M",` on the next line after pool url. 
+
+# Stress test
+
+You can also run continuous stress-test that is as close to the real RandomX mining as possible and doesn't require any configuration:
+```
+xmrig --stress
+xmrig --stress -a rx/wow
+```
+This will require Internet connection and will run indefinitely.

+Version 2.2.0
+-------------
+* API
+  + Add hwloc_bitmap_singlify_by_core() to remove SMT from a given cpuset,
+    thanks to Florian Reynier for the suggestion.
+  + Add --enable-32bits-pci-domain to stop ignoring PCI devices with domain
+    >16bits (e.g. 10000:02:03.4). Enabling this option breaks the library ABI.
+    Thanks to Dylan Simon for the help.
+* Backends
+  + Add support for Linux cgroups v2.
+  + Add NUMA support for FreeBSD.
+  + Add get_last_cpu_location support for FreeBSD.
+  + Remove support for Intel Xeon Phi (MIC, Knights Corner) co-processors.
+* Tools
+  + Add --uid to filter the hwloc-ps output by uid on Linux.
+  + Add a GRAPHICAL OUTPUT section in the manpage of lstopo.
+* Misc
+  + Use the native dlopen instead of libltdl,
