+### Building for default configuration
+
+A helper script `build_default.py` is provided to configure and build all the
+applications. It configures the project with default settings i.e., for `mps3`
+target and `sse-300` subsystem. Under the hood, it invokes all the necessary
+CMake commands that are described in the next sections.

+Additional command line arguments supported by this script are:

+ - `--skip-vela`: Do not run Vela optimizer on downloaded models.
