It has been exactly two months since I moved to Munich. The city is great and I am adapting very well to the new environment. Everyday I learn something here and fortunately I am able to help newcomers with my experience as well.
One of the first things that people ask when arriving in Munich is: how/ where do I find a home? The biggest pain in Munich is house as rentals are very expensive and it is difficult to get a place. So, my first advise would be to tell everyone you know that you are looking for an apartment and ask their help. Secondly, look up at German real estate websites, such as https://www.immobilienscout24.de/Suche/de/bayern/muenchen/wohnung-mieten

Another issue for a newcomer could be networking. In this sense, I strongly recommend joining some groups in social medias like Facebook. For example, the “Munich International Friends” group is a nice starting point for you to ask questions and look for tips in general.
Moreover, there are some very useful websites to enrich your knowledge about the town, its culture and so on. I can name here the ones I find most informative and that I usually access: Munchen.de (https://www.muenchen.de/) and Toytown Germany (https://www.toytowngermany.com/munich/)
Last, but not least, the language! If you are not a German speaker, you should start studying German as soon as possible! Even though Munich is a very international city and many people can speak English, learning German is a must. Why? Because it will open more possibilities for you and help you integrate locally. Here, my tip for you would be to enroll in DeutschAkademie. 
To conclude, Munich is a beautiful city and it can treat you very well. If you are starting a new life here, I really hope you are able to enjoy the parks, the river, the beer gardens, the cultural activities and more! 

Cheers,
