+The first content for your repository for the definitions of the '$_BOOT_DOMAIN' domain has been created.
+
+Please create a definition repository.
+To follow the naming convention name it '$_REOPSITORY_NAME'
+
+Please DO NOT use the SSH key of root for this.
+Maybe you can use https and user password for pushing the first commit.
+
+Go to folder '/tmp/skeleton/definition' and check the content of all 'authorized_keys' files,
+correct them if required to prevent losing access to your hosts.
+
+The public ssh key of your jenkins server has to be added.
+
+Only now follow the instructions as our git server shows.
+For example:
+
+  cd /tmp/skeleton/definition
+  git init
+  git checkout -b main
+  git add .
+  git commit -m "first core definitions"
+  git remote add origin https://git.example.dev/[SOME_PATH/]$_REOPSITORY_NAME.git
+  git push -u origin main
