The Global 21-cm signal from neutral hydrogen in the intergalactic medium is expected to shed light on the appearance and evolution of the first stars, galaxies, and black holes in the Universe. It will thus represent a key probe of the Dark Ages, Cosmic Dawn, and the Epoch of Reionization. In 2018, the EDGES experiment reported an exotic tentative detection of this signal. Recently, other experiments have made steady progress toward testing this tentative detection, including SARAS3, which has reported the first non-detection. Understanding the origin of the EDGES signal and reaching a conclusive, high-precision detection of the global 21-cm signal from the early Universe motivates the 21-cm cosmology community to keep improving on our experimental (including ground- and space-based), theoretical, and modelling efforts. This workshop will serve as a forum to discuss all the recent progress and results. We will have talks and sessions discussing the most important aspects, as well as raising and addressing the key concerns. We look forward to enlightening interactions, debates, and lessons.
