Forem dev

I've created a new branch call forem_dev for testing the installation of the engine forem on the project.
This branch has been merged with the dev branch just before creating this fork (i don't have access to create the branch on simplon.co so i forked the project... Well, that's an exercice, isn't it ?).

I was wondering is the readme should be updated with some instruction about this new branch. I don't know, that's an idea...
