Merging dev into master
As I will begin working on the documentation, one of my first recommandation is to update the master branch according to the state of the current dev one which is the official state of the project.
It will able me to work on a proper documentation branch, and developers to work on specific features branches.
Using a semantic branch name related to the feature it adds or the bug it fixes could help figuring out what's going on.
