 ## How to install
 
+### Environment
+
+I can support you with issues best if you use **Alpine Linux**. In my experience, **2-4 GB RAM** should do nicely.
+
 ### New Installation
 
 1) Make sure you have Python 3.5 or higher installed. You also need some basic packages that should be present on most systems, but I've provided simple shell scripts for Alpine and Ubuntu to get everything you need.
