WebBaseLoader unable to load github pages

When I try WebBaseLoader with github pages as shown by notebooks here I don’t see the actual data but something like:

Skip to content
          Sign in

etc. My feeling is that it might got to do with restriction that github has for crawlers accessing its data even if it is in public pages. Is that the correct understanding or I am missing something? Also has anyone got it working if so how?

Never mind. It works alright. There is a lot more on the page that this loader correctly returns than what meets an eye on gitHub which was the original cause of the confusion.
