How to start in metaverse?

How do I embark on the journey of entering the metaverse? Is it as simple as downloading an app or is there a more complex process involved? Do I need to have a certain level of technical knowledge or can I navigate the space with ease as a novice? Are there any prerequisites or essential tools that I should acquire before diving in? And perhaps, are there any recommended platforms or communities that I should join to better understand and engage with the metaverse?
