+# Build instructions
+
+MeshLab requires [Qt](https://www.qt.io/) >= 5.9, with "script" and "xmlpatterns" as additional packages.
+
+After setting up the Qt environment:
+
+	git clone --recursive https://github.com/cnr-isti-vclab/meshlab
+	cd src
+	qmake
+	make
+
 Compiling instructions can be found in the [src](https://github.com/cnr-isti-vclab/meshlab/tree/master/src) folder or simply looking at the continous integration setup on [Github Actions](https://github.com/cnr-isti-vclab/meshlab/actions), [travis](https://travis-ci.org/cnr-isti-vclab/meshlab/builds) and [appveyor](https://ci.appveyor.com/project/cignoni/meshlab/history).
