Using Web Forms for Agreement Signature

Hello, hello! I’ve watched several videos and reviewed documents on this subject and cannot find my way around completing this.

Is web forms the appropriate tool to use to send an agreement to a large group of volunteers who need to review, sign, and opt in/out of a few activities? I’ve successfully used power forms for this, but the web form option is so much better for mobile use, I’d love to use it. 

Is there a recommended video or step by step guidance doc you could point me to? I’m trying to pull in the text of the agreement.

Thanks is advance.
