Please make use of available resources before posting questions like this: the community is very helpful but doing your own research first both respects the time of others, and improves your own understanding.
there’s a bunch of information on the wiki and in GitHub that is easy to find http://lmgtfy.com/?q=Mavros+ardupilot
Plus a bunch of YouTube, from Randy, Pierre, Tizzy and others.
When you’ve worked through that stuff, if you’re having issues, posting specific questions about specific problems will enable the community to best help.
