It really depends on your goals
The steps you take are the same no matter what, the topics vary based on your goals.
In a nutshell, do some research to find out what skills are needed, and do a lot of projects and self-study using those skills. Do projects by yourself, volunteer for open source projects, volunteer to work at charities, or work for free at a place... it doesn't matter, but go get some real world, hands on experience.
