echo ""
echo "Switching to project docroot."
cd /var/www/project-name/public_html

===== En locale =====

==== ajouter le remote du serveur dans votre depos git existant ====
Il est possible de remplacer serveur.com par l'ip du serveur
<code bash>
git remote add project-name username@serveur.com:gitBareRepos/project-name.git
</code>
==== créer une branche prod ====
<code bash>
git branch prod
</code>
==== travailler sur la branch master (ou autre) et synchroniser la branch prod ====
<code bash>
git fetch . master:prod
</code>
==== pousser la prod en ligne ====
<code bash>
git push project-name prod
</code>

et voila !
