 To build the RPMs:
 - Checkout (clone) the Git repository
 - Create the `~/rpmbuild/SOURCES` directory
-- Create a tar archive.  For example, from within the cloned directory you can use `git archive --output ~/rpmbuild/SOURCES/ngcp-mediaproxy-ng-<version>.tar.gz --prefix=ngcp-mediaproxy-ng-<version>/ master` (where <version> is the version number of the master branch)

 Once the build has completed the binary RPMs will be in `~/rpmbuild/RPMS`.
