Does anyone knows what the hell is "coala" that's used for liting and fixing code? Cause I am pushing something and they said I need to fix my code using "coala" but I can't seem to figure it out what it is, how to install... I even tried to install in atom as plugin but that shit gives errors.

Hello all, I know we can search in git lab for the labels(easy, first commit etc) to find open source projects that suit me, but as a rookie it gets a bit frustrating not understanding the project and so on. Does anyone know a better way to contribute to open source and learning at the same time?
