+
+## How to build
+
+**Warning**: building Shotcut should only be reserved to beta testers or contributors who know what they are doing.
+
+### Qt Creator
+
+The fastest way to build and try Shotcut development version is through [Qt Creator](https://www.qt.io/download#qt-creator).
+
+### From command line
+
+First, check dependencies are satisfied and various paths are correctly set to find different libraries and include files (Qt, MLT, frei0r and so forth).
+
+#### Configure
+
+In a new directory in which to make the build (separate from the source):
+
+```
+cmake -DCMAKE_INSTALL_PREFIX=/usr/local/ /path/to/shotcut
+```
+
+We recommend using the Ninja generator by adding `-GNinja` to the above command line.
+
+#### Build
+
+```
+cmake --build .
+```
+
+#### Install
+
+If you do not install, Shotcut may fail when you run it because it cannot locate its QML
+files that it reads at run-time.
+
+```
+cmake --install .
+```
