  1. This is a page about the metamath proof assistant. I’m not very expert but it’s a start.

    Also, I took the liberty of moving the sentence about who created Metamath, and the available libraries, to a References-section. Please check if you are happy with the result.

    Hi this is Roger Witte confirming that I am content with your changes

  5. I added a reference to some other recent work with metamath. I was visting their page and they were complaining that I had mentioned Stephen O’Rear’s work but Ignored Mario’s. I am afraid that it was 100% ignorance on my part

  6. The paragraph about how definitions can introduce contradictions is only about the proof verifier itself and thus is largely out of date. Describe the definition checker in hopefully the right amount of detail. See https://us.metamath.org/mpeuni/mmset.html#definitions for more on this topic (as a sub-page of the metamath home page, already cited, perhaps this doesn’t need its own link).
