Thank you.
It's just like inline linking in html/css. You use one # for all headings. Then no space between the # and the anchor name. The anchor tag names must be in lowercase, and delimited by dashes if multi-word.
Eg.
[click on this link](#my-multi-word-header)
###My Multi Word Header
Then I think(I can't rmmbr) if there are multiple headers with d same name, you will add number at the end of it.
Eg.
[click on this link](#duplicate-header1)
[click on this link too](#duplicate-header2)
##Duplicate Header
###Duplicate Header
