+Repository containing cross-compilation toolchain for the smart garden project
+
+## Usage
+
+Using this toolchain **REQUIRES** it to be located at
+
+    ``` /opt/x-tools-smartg ```
+
+Any other location wont work, due to QT5 searching for hard coded paths.
+
+It is not necessary to add this directory to your PATH variable, unless you
+decide to use this toolchain for other projects, which is possible.
+
