+.SYNOPSIS
+  Helper script to build OpenPype.
+
+.DESCRIPTION
+  This script will detect Python installation, and build OpenPype to `build`
+  directory using existing virtual environment created by Poetry (or
+  by running `/tools/create_venv.ps1`). It will then shuffle dependencies in
+  build folder to optimize for different Python versions (2/3) in Python host.
+
+.EXAMPLE
+
+PS> .\build.ps1
