Making custom EULAs

Are there any videos going over making an EULA? I know its not right to copy and edit the standard Apple one (although I’ve seen a lot that look similar to theirs), so Im wondering is there a site that is trusted or some sort of process to do this the right way?

My app got rejected and this is the reason: Require that users agree to terms (EULA) and these terms must make it clear that there is no tolerance for objectionable content or abusive users

Seems like is a good source.
