 - Clone the releng repo if you do not already have it:
 
-::
-
     git clone https://pagure.io/releng.git
 
 - If you already have it, pull the latest changes:
 
-::
-
     pushd releng && git pull --rebase && popd
 
 - Clone the <foo> package locally:
 
-::
-
     fedpkg clone <foo>
 
 - Checkout the <branch> branch:
 
-::
-
     cd clone && git checkout <branch>
 
 - Run the script:
 
-::
     python ../releng/scripts/distgit-branch-unused.py <branch>
 
 (If needed, see the ``--help`` of the script for more information)

 - Go to pkgs01 as root
 
-::
-
     ssh pkgs01.iad2.fedoraproject.org
 
 - Go to the git repository:
 
-::
-
     cd /srv/git/repositories/<namespace>/<foo>.git
 
 - Move the head of the branch (this allows to recover it later if needed):
 
-::
-
     mv refs/heads/<branch> heads_<branch>
 
 - On your local clone of <foo>, check that the branch was deleted upstream:
 
-::
-
     git fetch -p
 
 This should show something like:
 
-::
     $ git fetch -p
