+Building HandBrake for BSD
+==========================
+
+If you have installed a HandBrake package from your distribution or other third-party package repository, please remove it before proceeding. See the section, *Warning about broken third-party builds* on [Where to get HandBrake](../get-handbrake/where-to-get-handbrake.html) for more information.
+
+## Installing dependencies
+
+Dependency installation instructions are available for the following distributions.
+
+- [FreeBSD](install-dependencies-freebsd.html)
+
+## Building HandBrake
+
+Clone the HandBrake repository.
+
+    git clone https://github.com/HandBrake/HandBrake.git && cd HandBrake
+
+Build HandBrake. Since only the command line interface is supported on BSD, the graphical interface is automatically disabled (equivalent to `--disable-gtk`).
+
+    ./configure --launch-jobs=$(sysctl -n hw.ncpu) --launch
+
+When complete, you will find `HandBrakeCLI` in the `build` directory.
+
+Install HandBrake (optional).
+
+    cd build && sudo make install
+
+To start over, simply remove the `build` directory.
+
+    bash -c 'if [[ "$(basename $(pwd))" == "build" ]]; then cd ..; fi'
+    rm -rf build
