Or you can also let me know what needs to be changed, and I can make the adjustment from my end. 😉

[mtreacy002]

That'll be great, @nandini45. I'd really appreciate it 😉

[isabelcosta]

@mtreacy002 it would be great if someone could review this. As far as I know you can add this to wiki right?

[mtreacy002]

@isabelcosta. Yes, we can add this to wiki, but I have no access to anitab-org wiki so can't create a page for this. Should I just add it to docs folder as .md file for maintainers to upload to wiki?

Making it available as the discussion in PR linked shows very in-depth diagrams and not sure if they can be placed in wiki Maybe different contributors can add simple ones
