One of the highest priorities in particle physics today is the identification of the constituents of dark matter. This manuscript is a supplement to pedagogical lectures given at the 2021 Les Houches Summer School on Dark Matter. The lectures cover topics related to the direct detection of WIMP dark matter, including the distribution of dark matter, nuclear scattering, backgrounds, planning and designing of experiments, and a sampling of planned and ongoing experiments.

List of changes

Changes in response to Reviewer 1:
1-general: the Sun when referred to the name of the star in our Solar System should be written in a capital letter
2-page 10 the generates --> that generates
3-page 22: about-->around
3-page 23: interactions to observe --> it should detections because this can be dependent on the detection efficiency
sentence has been re-worded
4-figure 11: specified in the figure what are the dashed and continous lines represent
5-page 24: O(1) times larger --> does it mean it is of the same level? please clarify
sentence re-worded
6-page 25: changed "side effect" radiological backgrounds to as muon-induced background or cosmogenic backgrounds
7-page 27: of the atomic electrons --> off the atomic electrons
10-page 33: our airborne radioisotopes --> out airborne radioisotopes
11-page 33: to passively reduce --> or to moderate neutrons
12-page 33: radiognic -->radiogenic
14-page 39: added radon to the list of contaminants that are reduced by distillation techniques in liquid nobles
16-page 40:discussion of cosmic ray interatctions
19-figure 25: increased figure size
20-figure 25: added list of models in figure 25 to the main text.
21-page 47: avrage --> average
22-page 48: Mentioned the SABRE project and the interest to have a dual detectors in both emispheres
page 48: changed LUX/LZ: to LZ
page 48: clarified time drift information between S1 and S2
23-page 48: further accelerated through a stronger electric field
24-page 52: is s strong --> is a strong
25-page 55:are sensitivity --> are sensitive
26-page 56: evetns -->events
27-page 58: fixed typo with a link address (removed the link address)
28-page 58: E basis --> ER basis
29-page 58: specify the location of LSM
30-page 58: discuss briefly why the resolution and backgrounds from "heat-only" events are limiting factors
31-page 61: TEX --> TES
32-page 62: fixed Figure 42 refernece
33-page 63: specified the legend in figure 42
34-page 62: removed figure 43

Changes in response to reviewer 2:
Page 9 fixed typo "detector" -> "detect"

Changes in response to reviewer 3:
1 - added more references on page 4 to discussion of dark matter distribution.
2 - revised text to referring to WIMP
3 - page 5: Note in paragraph following equation 7 that inelastic scattering is possible and added reference.
4 - pg 15: Paragraph following equations 87-88 summarizes the situations under which those equations are valid.
