+# RandomX Service
+
+RandomX Service provides a simple HTTP API to calculate [RandomX](https://github.com/tevador/RandomX) proof of work (PoW).
+
+## Use cases
+
+* Fast PoW verification for Node.js based pools
+* Web-mining with explicit user consent (see below)
+* Access to RandomX for clients who cannot link directly to librandomx
+
+## Building
+
+### Linux
+Prerequisites: cmake, make, gcc
+```
+git clone --recursive https://github.com/tevador/randomx-service
+cd randomx-service
+./build.sh
+```
+
+### Windows
+Prerequisites: cmake, Visual Studio
+```
+git clone --recursive https://github.com/tevador/randomx-service
+cd randomx-service
+build.cmd
+```
+
+## Usage
+
+```
+Usage: ./randomx-service [OPTIONS]
+Supported options:
+  -host <string>     Bind to a specific address (default: localhost)
+  -port <number>     Bind to a specific port (default: 39093)
+  -threads <number>  Use a specific number of threads (default: all CPU threads)
+  -flags <number>    Use specific RandomX flags (default: auto)
+  -origin <string>   Allow cross-origin requests from a specific web page
+  -log               Log all HTTP requests to stdout
+  -help              Display this message
+```
+
+## RandomX Service API
+
+The service provides the following API methods:
+
+* `GET /info`
+* `POST /seed`
+* `POST /hash`
+* `POST /batch`
+
+Refer to [doc/API.md](doc/API.md).
+
+## Web-mining
+
+To allow requests from the browser, use the `-origin` command line option. For example, to allow the site https://example.com to access the service, this command line option should be used:
+
+```
+./randomx-service -origin https://example.com
+```
+
+### Notes
+* using the `/batch` API, web-miners are able to reach similar performance as native miners
+* HTTP requests to localhost from HTTP websites are currently blocked by [Firefox](https://bugzilla.mozilla.org/show_bug.cgi?id=1488740) and [Safari](https://bugs.webkit.org/show_bug.cgi?id=171934), but this behavior may change in the future (refer to the linked bugtrackers).
