 If you want to run and build packages in the staged-recipes repository locally,
 go to the root repository directory and run the
-``.scripts/run_docker_build.sh`` script.  This requires that you have docker
-installed on your machine.
+``build-locally.py`` script (you need Python 3). And then you could follow the prompt to select the variant you'd like to build. This requires that you have Docker
+installed on your machine if you are building a package for Linux.
+For MacOS, it will prompt you to select a location for the SDK (e.g. ``export OSX_SDK_DIR=/opt``) to be downloaded.
 
-You need to define an environment variable named ``CONFIG``. Its value must be
-the name of one of the three YAML configuration files in the ``.ci_support``
-directory (either ``linux64``, ``osx64``, or ``win64``). As an example, you can
-invoke the command as follows.

-    $ CONFIG=linux64 ./.scripts/run_docker_build.sh
+If you know which image you want to build, you can specify it as an argument to the script.
