Documentation link points incorrectly

Hi,

sorry to post this question here, I know this is not the correct place. I am looking at ExcelDNA and trying to find the documentation . However, in the main website (https://excel-dna.net/ or https://excel-dna.github.io/) and in the github pages whenever I find the documentation link it directs me to https://archive.codeplex.com/?p=exceldna. This is the home page in codeplex and I can not see any further documentation.

I was looking for API docs and tutorials and high level of how the internals work. I have found https://github.com/Excel-DNA/ExcelDna/wiki, however, as I can't see docs for the high level and see the basic functionality this is too indepth for me.

I tried to post to google groups twice but my post does not appear. Not sure why

Thanks
Matt
