It is possible to attach DISQUS comments to blog site.
Setup your DISQUS Account
Before you can use the commenting stuff, you need to register into Disqus. There you find a lot of disqus documentation that you simply not need :-) . Pelican already has done that for you.
Register on DISQUS site
Select ‘I don’t see my platform listed, install manually with Universal Code.
Remember ‘Shortname’=kamyanskiy, it will be used later in site configuration. Fill fields Website name and Website URL.
Check ‘Allow guests to comments’
Finish settings with Add trusted site, my own is kamyanskiy.github.io
Into pelicanconf.py file enable DISQUS, just add these settings:
DISQUS_SITENAME = "kamyanskiy"
Remember, here should be added ‘shortname’ from step 3.
That’s done, now generate content and check that comments working fine:
