How to wrap BTC to WBTC?

Could you kindly elaborate on the process of wrapping Bitcoin (BTC) into Wrapped Bitcoin (WBTC)? I'm interested in understanding the steps involved, as well as any prerequisites or considerations that I should be aware of before engaging in this conversion. Could you also explain the role of trusted custodians in this process, and how they ensure the security and authenticity of WBTC tokens? Thank you for your assistance in clarifying this matter.
