Hey, abdennour! I've added your two last pull requests to a milestone https://github.com/ehpc/bootstrap-waitingfor/milestones so I could fix it and test it later, alternatively you could follow cotributing guidelines in README and make a proper pull request which will pass all required tests so I could accept it easily. Thanks!
