track markers

Hello
I’m trying to mark beginings of chapters, but can’t seem to be able to import track markers from txt files.
I can’t find any online-guide that explains how to import markers from a txt/xls.
can someone help?

“Markers” in Audacity are called “Labels”. What they are and how to use them is documented in the manual here: http://manual.audacityteam.org/man/label_tracks.html
