@ -116,6 +116,22 @@ To get the VPP sources that are used to create the build, run the following comm
$ git clone https://gerrit.fd.io/r/vpp
$ cd vpp
As VPP version is derived from git description (which is based on git tags),
if the github generated tarballs are used, the version information
will be missing from the version file (.../src/scripts/.version)
which is required by the version script when building
in a non-git based workspace or the build will fail.
In that case, put the desired version string into
.../src/scripts/.version to satisfy the requirements of the version script.
Alternatively, the ``make dist`` command in a cloned git workspace
will generate an xz compressed tarball of the source
including the .../src/scripts/.version file containing the git hash
using the standard nomenclature for VPP images.
Extract the tarball using the -J option to decompress it using xz. For example,
``tar xvJf ./build-root/vpp-23.10-rc0~184-g48cd559fb.tar.xz``
