How can I buy shares directly?

I'm curious about the process of buying shares directly. Could you please explain to me the steps I need to take in order to make a direct investment in shares? Is there a specific platform or broker I should use? Also, what are the benefits and potential risks associated with buying shares directly compared to other investment options? Additionally, are there any regulations or legal considerations I should be aware of before making a direct investment in shares? I'd appreciate your insights on this matter.
