+# Deploying portable **XMR-Stak** on Linux systems
+
+XMR-Stak releases include a pre-built portable version. If you are simply using it to avoid having to compile the application, you can simply download **xmr-stak-portbin-linux.tar.gz** from our [latest releases](https://github.com/fireice-uk/xmr-stak/releases/latest). Open up command line, and use the following commands:
+
+```
+tar xzf xmr-stak-portbin-linux.tar.gz
+./xmr-stak.sh
+```
+
+Configuration and tuning files will be generated automatically from your answers.
+
+For automatic deployments, please use the steps above to obtain config.txt and use the following script:
+
+```
+#!/bin/bash
+curl -O `curl -s https://api.github.com/repos/fireice-uk/xmr-stak/releases/latest | grep -o 'browser_download_url.*xmr-stak-portbin-linux.tar.gz' | sed 's/.*"//'`
+curl -O http://path.to/your/config.txt
+tar xzf xmr-stak-portbin-linux.tar.gz
+./xmr-stak.sh
+```
+
+XMR-Stak will auto-configure and go to work. You don't even need Docker!
