+## System Requirements
+
+This crate requires a native installation of the [Eclipse eCAL](https://github.com/eclipse-ecal/ecal) C/C++ runtime, version 6.0 or newer. General instruction for the installation you can find [here](https://eclipse-ecal.github.io/ecal/stable/getting_started/setup.html).
+
+On Linux:
+- Make sure `libecal.so` and headers are available in your system paths.
+
+On Windows:
+- Set the `ECAL_HOME` environment variable to the root of your eCAL installation.
+
+This crate will fail to compile if the native libraries are not found.
