We describe plans for the development of the Southern Wide-field Gamma-rayObservatory (SWGO), a next-generation instrument with sensitivity to thevery-high-energy (VHE) band to be constructed in the Southern Hemisphere. SWGOwill provide wide-field coverage of a large portion of the southern sky,effectively complementing current and future instruments in the globalmulti-messenger effort to understand extreme astrophysical phenomena throughoutthe universe. A detailed description of science topics addressed by SWGO isavailable in the science case white paper [1]. The development of SWGO willdraw on extensive experience within the community in designing, constructing,and successfully operating wide-field instruments using observations ofextensive air showers. The detector will consist of a compact inner array ofparticle detection units surrounded by a sparser outer array. A key advantageof the design of SWGO is that it can be constructed using current, alreadyproven technology. We estimate a construction cost of 54M USD and a cost of7.5M USD for 5 years of operation, with an anticipated US contribution of 20MUSD ensuring that the US will be a driving force for the SWGO effort. Therecently formed SWGO collaboration will conduct site selection and detectoroptimization studies prior to construction, with full operations foreseen tobegin in 2026. Throughout this document, references to science white paperssubmitted to the Astro2020 Decadal Survey with particular relevance to the keyscience goals of SWGO, which include unveiling Galactic particle accelerators[2-10], exploring the dynamic universe [11-21], and probing physics beyond theStandard Model [22-25], are highlighted in red boldface.
