The support team will enable the account and send you a confirmation as soon as possible. ==== Updating the repositories from BELK 2.1.0 ==== {{ImportantMessage|text=To '''update the repositories from BELK 2.1.0''', the following commands should be used:}} <pre>git fetch origingit checkout -b <new_branch_name> origin/bora</pre> ==== Synchronizing the repositories ==== When the account is enabled, you can synchronize a source tree entering the repository directory and launching the <code>git fetch</code> command. Please note that <code>git fetch</code> doesn't merge the commits on the current branch. To do that, you should run the <code>git merge</code> command or replace the ''fetch-merge'' process with a single <code>git pull</code> command. Please note that the recommended method is the ''fetch-merge'' process.
