 ## About
 This is a node.js wrapper for snap7. Snap7 is an open source, 32/64 bit, multi-platform Ethernet communication suite for interfacing natively with Siemens S7 PLCs (See [compatibility](http://snap7.sourceforge.net/snap7_client.html#target_compatibility)).

     npm install node-snap7
 
-Requirements:
+node-snap7 uses `prebuild` and `prebuild-install` for handling prebuilt binaries. See [this list](https://github.com/mathiask88/node-snap7/releases) of supported prebuilt platform binaries. When installing node-snap7 `prebuild-install` will install prebuilt binaries from GitHub if they exist and fallback to a compile step if they don't.
+
+If you don't want to use the `prebuild` for the platform you are installing on, specify the `--build-from-source` flag when you install.
+
+For building from source you need the following requirements:
 
  - Windows:
     - Visual Studio 2010 Express or higher e.g [Visual Studio 2015 Express](https://www.visualstudio.com/de/vs/visual-studio-express/)
