Where can I buy ARK ETF?

Excuse me, could you possibly enlighten me on where one might be able to acquire shares of the ARK ETF? I've heard a lot about its focus on disruptive innovation and I'm quite intrigued by the prospect of investing in it. Are there any specific platforms or brokers that you would recommend for purchasing shares of this ETF? Additionally, are there any fees or commissions associated with purchasing it that I should be aware of? I would greatly appreciate any guidance you could provide in this matter.
