welcome to the community! You can post here all MongoDB related questions. Please do not post any private or confidential information. You ask in public and we, as a community, will try to get you an answer. I like to point you to the Getting Started with the MongoDB Community from @Jamie which should answer all questions. If not, do not hesitate to ask here.
