How do you actually meditate?

So, for this thread, I'm specifically not asking for detailed explanations about the spiritual or philosophical aspect that goes behind your motivations to meditate. A brief explanation is almost certainly required, though.

Mostly, I wish to know practical things, details that often go unsaid, like:

• What kind of meditation do you practice?
  • How can I Google it?
• Where and when do you meditate, and why?
• Do you do it alone?
• How do you prepare for meditation?
• What you do afterwards?
• How frequently do you meditate, and for how long?
• If you sit at all, in what position do you sit?
  • Where do you sit? The ground, a mat, a cushion, a chair, your bed?
• Do you keep your eyes closed or open?
• Do you concentrate on your breathing?
• Do you breath through your mouth or nose?
• Do you count your breaths or visualize them in any way?
• Is there any particular breathing technique involved?
• Do you use any aid such as noise generators, soundscapes, timers, meditation apps, etc?
• Do you push thoughts away?
• Do you concentrate on any object, physical or otherwise?
  • statues, amulets, images, mental images, mantras, etc.
• What do you do if...
  • your legs go numb?
  • there's a fly on your nose?
  • there's mucus on your mouth or throat?
  • you must cough or sneeze?
  • you're itchy all over?
