The steps to stepping into a leadership role are largely two-fold:

- Express to your manager your interest in stepping into a leadership role over the next 6-12 months.

- Write down a list of responsibilities / behaviours a good leader has in your company. Take on one of these responsibilities one at a time to show that you both interested and serious about a leadership role. Advertise to your manager how you are progressing with these extra responsibilities each month via email so they had a written record.

A leadership role has much higher responsibilities and so your manager (if they are a good manager) will not promote you into the role without knowing you can do the job first. Leaders lead by action, not be theory. I know some great leaders who have a very poor theoretical understanding. And I know some horrible leaders who know the theory inside out.

Focus on action.
