I'm not sure the the two changes here are necessary. The addition of a comma there is not very substantial in the understanding of the sentence in my opinion and the use of "actively" instead of "active" I feel is more appropriate as it acts as an adverb to the verb of "learning" and "participating".

@hiteshvijayhv I would suggest looking at open issues with specific problems to solve if you are interested in contributing to the project. Thanks.
