The lecture notes on “Sterile Neutrinos as Dark Matter Candidates” are written clearly and accurately, and represent an excellent introduction to the subject, complete with bibliography.

I would like to suggest a small number of minor editorial corrections, listed I the pdf file attached.

(in reply to Report 1 on 2021-09-26)

I would like to thank the referee for their careful reading and detailed comments / suggestions. They will all be incorporated in the next version of the manuscript, with the exception of the very first one:

'Page 4, second line after Eq (16): “This would have led ...” should be replaced with “An alternative assumption X would have led ...”, where X is an assumption different from the one mentioned in the previous line.'

The sentence is correct as it is - the statement about the modified phase factor refers to the (somewhat unjustified) equal-momentum assumption, not to yet another alternative assumption.

I attach a PDF that highlights the changes made in response to this referee report, as well as to a list of very detailed and useful comments submitted by Pueh-Leng Tan, one of the students who attended the lectures at the Les Houches School.
